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.’

When that てこそ is replaced with だけで, it will change the nuance to ‘Becoming a parent is the only thing necessary to understand that children are miracles.’ As you can see here, だけで does not carry the nuance of ‘unless…/only after…’, so it can’t replace てこそ without changing the nuance of the sentence completely.

We hope that answers your question!
