I suggest the asker give this word ?? in a sentence so that we can focus on its usage through context.
Yes. It is a nonstandard form of the verb 'converse.'
No, "joyness" is not a proper word in standard English. The correct term to convey the feeling of joy is "joyfulness" or simply "joy." "Joyness" appears to be a nonstandard or invented term that does not align with traditional language conventions.
No, "areosecond" is not a recognized word in the English language. It may be a misspelling or a nonstandard term.
"Octopussed" is not a standard word in the English language. It is likely a nonstandard or informal term, possibly used colloquially or creatively to describe something being affected or manipulated by an octopus.
Yes, its meaning depends on in which dictionary you look the word up.
The term "interestee" is not a standard English word found in most dictionaries. It appears to be a derivative of "interested party" or "interested party," which are commonly used legal terms. While it may be understood in certain contexts, it is not widely recognized and may be considered nonstandard or jargon.
The difference is that theirselves is not a word. It is used very casually, but in formal settings or when with people who are well read, the word theirselves sounds very unrefined.
"There are" can be contracted to "There're", although this is not a standard American English term.
I believe the correct term in U.S. Customary.
"Dian" does not have a standard English definition. It could be a name or a term in another language.
"Kogw" does not have a standard English meaning. It is possible that it is a typo or a term from a specific context or language.
"Standard English" is the literary dialect used in formal writing and in the speech of well educated persons. It descends from the West Saxon dialect of Old English, specifically the dialect of London. "Non-standard English" includes many regional dialects, whose grammatical forms and words ( such as ain't and varmint, for example) are not exactly incorrect but are unsuited to formal discourse; and the non-regional dialect known as Black English ( or Ebonics ) which has a prominent substrate of African grammar. There is another literary dialect called Scots ( or Lallands or Doric ) which is considered non-standard because descends from the Anglic dialect of Old English, not the Saxon.
