Rated 5 out of 5 stars

A brilliant addition that TB needs ( if you write in English and not American). It just works so well. Only slight quibble is with 's. In its word list it seems to list every word in two versions, without and with the 's rather than just ignoring the 's ending. And sometimes these 's endings are dubious - certain words are never likely to need a possessive form and are so obscure that in the unlikely event that someone did need to write about, say "the muctate's appearance" they'd know- And words that normally end with s ( like plurals) should should be s' e.g the boys' houses.

This review is for a previous version of the add-on (3.1.7). 

Dear brother,

Thank you for your kind words.

Regarding the possessives, they have to be added by hand.

So, I am going through all words, checking which ones are nouns and adding possessives to them.

Certain words I do not add possessives, special words such as Taxonomic and time eras.

You are right about the plurals. I have been adding possessives to them because I have noticed that now-a-days in English texts, some people write: “the boys's houses” instead of the “the boys' houses”, but I will start fixing it for the next versions. It will take me a few months to have it done.

I couldn't find “muctate”, but some words are tricky, such as “OBE's” (Out of Body Experiences): “An OBE's a good experience”, so it could be using “'s” as a possessive or as an “is”.

So much that needs to be done!

Thank you again for the kind words!
