[ROBERTMIC]

Hi everyone. I,m robertmic from lagos and I,m struggling to learn english. Please help Is this sentence correct;
"All efforts made in contacting him was to no avail"
when do you use "was" and "were"

[Tdol]

It should be 'were' beause you have 'efforts', which is in the plural. I'd say the following:
All efforts made to contact him were to no avail.

[ROBERTMIC]

"Efforts", in the sentence above, is plural, so, "were" is appropriate.
