About ~てこそ

In a similar way to how the particle こそ highlights a particular word as being the 'precise' or 'exact' reason for something, its combination with the て-form of a verb will indicate that (B) is absolutely reliant on (A). This reliance can be translated in several different ways, and will usually become clear in the (B) part of sentences. Standard interpretations include 'only if (A), (B)', 'unless (A), (B)', or 'until (A), (B)'.

The reliance that (B) has on (A) can be translated in several different ways, but the most common interpretations are that (A) will determine either the outcome, assessment, or evaluation of (B), based on the speaker's opinion, values, or understanding of the situation.

        Is this interchangeable with Verb + ことだけで ?

        Hey @ljoekelsoey !

        This grammar point is not interchangeable with だけで. The ‘just by’ translation of てこそ has the nuance of ‘until…/unless…’, which だけで does not have.

        Let’s look at this sentence for example:

        になってこそ子供奇跡だというかる。The translation on the site is ’ Only by becoming a parent, you can understand the mindset that children are miracles.’, but the nuance this sentence carries is ’ Unless you become a parent first, you wont understand the mindset that children are miracles.’
