I would like inquire about the correct usage of preposition to/by after replace. for example:
Please replace this word to something else.
Please replace this word by something else.
Are these two sentences correct? If yes then what is the difference n meaning ?
First of all, replace something to something else is completely unidiomatic. Replace by sounds a lot better and generally would be a better choice of words, but you would typically say that in the passive voice: to be replaced by something or someone (e.g. He was replaced by the new mayor.). If you want to say that in the active voice, use replace with:
Please replace this word with something else.
