In the fifth sense, usually found in the archaic phrase no boot to moot, as inː it's no boot to moot with her (it is no use to talk/reason/plead with her).

In rural northern dialects of the UK, usually used together with the verbs mell and spell, where moot is used instead of talk and say; mell used instead of speak and converse; and spell instead of tell and relate. The verb moot in the sense to talk, say, utter etc., is part of an informal in-group speak or register wherein speakers (mostly of northern dialects) use this and the above-mentioned words when talking with one another and when talking with outsiders or strangers they, usually, only use the words like say, talk, speak etc. For example, if a mother is talking with her child she is much more likely to use words like moot, mell and spell, however if she is speaking with a stranger from the South she is extremely unlikely to use such words. Also, such words are usually considered taboo in formal contexts.
