Перевод - Персидский язык-Английский - كودكي ياد گرفتم كه مي خواست آب شور

Hi ghasemkiani,

I'd say:
"... because the unsaid words are what breaks the hearts."

What do you think?

Hello,

Thanks for the suggestion. Your expression sounds better, but shouldn't it be "are what break the hearts" (plural)? Besides, can we somehow insert the word "usually" in it?

On the other hand, the structure "it is ... that ..." is quite common and valid in English. My only doubt is about the "words" being plural and maybe somehow inconsistent with "it is".

Lilian,

Please see this translation, too:

"... because the hearts are usually broken by the words that remain untold."

This is an exact translation of the Persian source. Do you agree with this translation?

The verb could be plural in a different structure, ie:

"the unsaid words are those which break the hearts"
but 'what' takes a singular form, like in:
"Honesty and hard work are what matters"

And you can insert "usually", of course.

{edit} About that other version, yes it's fine to me. I'd just change "the words" into "those words" and "untold"' into "unsaid".

That's a beautiful thought.

Many thanks for all your valuable help, lilian canale. I changed "untold" to "unsaid", using the new version of the translation.
