Question

the world has never had a good definition of the word liberty, and the american people, just now, are much in want of one. we all declare for liberty; but in using the same word we do not all mean the same thing. with some the word liberty may mean for each man to do as he pleases with himself, and the product of his labor; while with others the same word may mean for some men to do as they please with other men, and the product of other mens labor. here are two, not only different, but incompatible things, called by the same name, liberty. and it follows that each of the things is, by the respective parties, called by two different and incompatible names—liberty and tyranny. (from \defining liberty\ by abraham lincoln) which definition of declare is used in this paragraph? 1. to clarify 2. to acknowledge 3. to voice support 4. to formally announce

Explanation:

In the context of "We all declare for liberty", the phrase "declare for" implies expressing support. "To voice support" fits this usage as it conveys the idea of stating one's backing for liberty. Clarifying (to clarify) would involve making something clear, which isn't the case here. Acknowledging (to acknowledge) is more about recognizing something, not actively showing support. Formally announcing (to formally announce) is too official - sounding for this context where it's more about personal expression of support rather than a formal proclamation.

Answer:

1. to voice support
