Thank you very much for all your replies. However the answers do not exactly match the meaning.
"Love makes [anything] grow." — This anything can be anything — a person, work, condition, anything you can think of. Whatever love touches, it makes it grow. I'd prefer ambiguity and mystery for the "anything" part. What "anything" is determined by the imagination of the reader.
The subject is "love", the verb is "make grow". Two words for an ambiguous "anything".
I am looking for a Latin translation of "love makes it grow" or "love makes things grow" or an appropriate word in Latin for "grow". This is for a tattoo which will be on the outer side of the arm between elbow and wrist.
I have only tried automatic Google Translation.
A Latin tutor suggested "Amor crescere fecit" for the translation of "Love makes [anything] grow". Can I have your opinions on this translation?
