Dear teachers and members:
I would like to know if the expression WORTH SOMEONE'S WHILE when followed by a clause or a sentence the verb must be in its base form or in its gerund one. If both are correct which one is used the most?
a) It was worth my while to study English phonetics and phonololy.
b) It was worth my while studying English phonetics and phonology.
1) It is woth your while to visit my mother.
2) It is worth your while visiting my mother.
Both forms work.
