Plural or apostrophe on special words?

If treeish is a noun, you would probably use treeishes for the plural. Using an apostrophe for a plural is almost always wrong.

Tech, no offense but 'Git' has mebbe a dozen meanings, while it isn't clear whether the term in q to be pluralized is 'treeish' or the Git word used in its place; whether it's Brit or US 'cause there might be a diff

Thanks that is helpful.

To be clear I mean the Git the version control software. Treeish is word to refer to a part of Git. Thanks

then almost hasta be an adj

No offense, Chtv, but I'm still in the dark. Did you mean to say, 'To be clear, I mean The Git, the version-control software'

Then 'a part of Git' must refer to a digital word (or group thereof) that can be described as 'treeish. ' My first reaction (after about an hour of confusion) is " 'treeish' words"

Your typical idio, however (me) might not know what 'treeish' means

I don't think the OP knows what 'adjective' means.

In the context of what I am writing, I think that the audience will know the word. That is a good point, though. It makes me even think more about my goal of being well understood. Thanks

Yea Pc probly so; only the few Intellectual Failures (me) who won't use Google every time are still in the dark
