dar al-Islam (noun) and dar al-harb (noun)
Arabic
Dar al-Islam
Territory of Islam; regions where Islamic law prevails.
The region in which Islam has ascendance. (EB)
House of peace:  Refers to the dominion of Islam, namely, any structure, be it a home, community, or state, that allows the free practice of Islam.  It is most commonly used to delineate countries around the world that are under Islamic rule and thus fully permit the majority expression of Muslim faith. (Audrey von Maluski, Brown University, 2007)
Grok:  This term refers to territories where Islamic law, sharia, is enforced, and Muslims can practice their religion freely.  Historically, it includes regions where Muslim rulers govern, providing an environment where Islamic principles are applied to governance, justice, and daily life.  It's not just about the majority Muslim population but more about the implementation of Islamic law.  Over time, the definition has also been interpreted to include areas where Muslims can live and practice their faith even under non-Muslim rule if they are allowed to do so freely. (Grok)

Dar al-harb
Territory of war; regions where Islamic law is not implemented.
Abode of war, the region into which Islam could and should expand. (EB)
House of war:  Refers to the dominion of war around the world.  Generally, it refers to any place that Islam cannot be practiced without persecution.  It also refers to a country that is not under Islamic rule, and is thus not amenable to the majority of its inhabitants practicing Islam. (Audrey von Maluski, Brown University, 2007)
Grok:  Describes regions where Islamic law does not govern, and traditionally, where there is no security for Muslims to openly practice their faith or where they might face hostility.  The label house of war stems from the historical context where there was a perceived or actual state of conflict between these areas and Islamic states.  However, the term does not necessarily mean active warfare; it simply signifies areas outside of Muslim control or influence where Islamic law isn't the norm. (Grok)

davenport (noun)
A large upholstered sofa often convertible into a bed. (MW)
A large couch or sofa, sometimes convertible into a bed. (CDC)
A large sofa usually convertible into a bed.  Exactly how people describe a davenport depends on where they arere from.  In some parts of the U.S., a davenport is an especially fancy sofa, while in others it is one that can be converted into a bed. (VC)
A large sofa, sometimes one that is convertible into a bed; after the A.H. Davenport Company, a furniture manufacturer in Boston in the 1800s. (AHD)

dawdle (verb)
Waste time; be slow.  Move slowly and idly. (NOA)
To idle, waste time; to be sluggish or lazy; to loiter, linger, dally. (OED)

debanking (noun) also de-banking
The act by a bank of closing someone's account because they are regarded as a risk legally, financially, or to the bank's reputation. (CD)
Grok:
Refers to the practice where banks or financial institutions terminate or restrict the banking services of an individual or organization.  This can include closing accounts, denying access to banking facilities, or refusing to open new accounts.  Reasons for debanking can vary, but common causes include:
Suspicion of fraud or illegal activities
Regulatory compliance issues, such as anti-money laundering laws
Reputational risk to the bank
Political or social views of the account holder which might be seen as controversial or risky by the bank
High-risk categorization due to the nature of the business or financial behavior
Debanking has become a topic of concern particularly when it involves individuals or groups whose activities or opinions are not illegal but are considered controversial or not aligned with the values or risk tolerance of the financial institution.  This practice raises questions about financial inclusion, freedom of expression, and the power dynamics between banks and their clients.
debank (verb):  To deprive someone of banking facilities. (CDC)

debunkering (neologism, verb)
Nautical term:  To offload unusable and/or volatile fuel or waste from a ship.  As opposed to bunkering, which means to load fuel into a ship's bunkers (containers for storing a ship's operating fuel). (RM)
Note:  By definition debunkering is to offload onto something else.  Otherwise, it could simply be jettisoned.  I include this term here because, as with the nautical term yar, it could be applied to a person.  For instance, one could debunker a volatile or useless spouse onto her lover.  You can also jettison a spouse; debunkering implies a landing platform or place to go, an arranged exit.  I first heard this use in the Netflix series Maestro in Blue (season two, episode five).
I once encountered a clever department manager who launched a debunkering operation for a useless employee in order to move said employee to another, unsuspecting department.  Of course, the new department would eventually learn of the problem and they would have to either endure the useless employee or go through the hassle of terminating her.
Grok has comments on the metaphorical use of debunkering as well.

A non-Muslim subject of a state governed according to the sharia who is granted the freedom to worship and is entitled to the protection of life and property by the state, although constrained to pay a special tax and not granted the full legal status accorded to Muslim subjects.  Used as a disparaging term for a non-Muslim who is perceived as behaving in a conciliatory manner toward Islam. (AHD)

dhimmitude (neologism)
Word coined by historian Bat Ye’or to describe the status of dhimmi peoples.  In Islam, after jihad concludes in a given area with the conquest of infidel territory, a dhimma, or treaty of protection, may be granted to the conquered People of the Book, historically, Jews, Christians, and Zoroastrians.  The dhimma provides that the life and property of the infidel are exempted from jihad for as long as the Muslim rulers permit, which has generally meant for as long as the subject non-Muslims, the dhimmi, prove economically useful to the Islamic state.  The Quran spells out the payment of the jizya (poll or head tax prescribed in Sura 9:29), which is the most conspicuous means by which the Muslim overlords exploit the dhimmi.  But the jizya is not merely economic in its function; it exists also to humiliate the dhimmi and impress on him the superiority of Islam.

Dunning-Kruger effect (psychological concept)
Designating a postulated cognitive bias whereby people who have little ability in, or knowledge of, a particular task or subject tend to overestimate their capabilities, while those who are highly skilled or knowledgeable may tend to underestimate theirs. (OED)

EB:
In psychology, a cognitive bias whereby people with limited knowledge or competence in a given intellectual or social domain greatly overestimate their own knowledge or competence in that domain relative to objective criteria or to the performance of their peers or of people in general.  The effect is explained by the fact that the metacognitive ability to recognize deficiencies in one’s own knowledge or competence requires that one possess at least a minimum level of the same kind of knowledge or competence, which those who exhibit the effect have not attained.  Because they are unaware of their deficiencies, such people generally assume that they are not deficient, in keeping with the tendency of most people to choose what they think is the most reasonable and optimal option.
(EB)

Grok:
A cognitive bias where individuals with lower ability tend to overestimate their competence in a specific area, while those with higher ability may underestimate their own competence.  Here's a breakdown of the effect:

Overestimation by the Incompetent:  People who are unskilled in a particular domain often suffer from illusory superiority, rating their ability as much higher than it actually is.  They lack the metacognitive ability to recognize their own incompetence because the skills required for competence are the same skills necessary to recognize competence.

Underestimation by the Competent:  Conversely, those who are highly skilled might underestimate their abilities because they mistakenly assume that tasks which are easy for them are also easy for others.  This can lead to an underestimation of their relative competence.
