Knowing French is irrelevant to the question
If I put:
add
into Google Translate I get:
ajouter
However If I put:
'fake, add, word'
into translate.google I get
'faux, add, mot'
Why should two commas make that much difference that it would not translate?
Interestingly putting
fake. add. word
gives you:
faux. ajouter. mot
