What does possibly mean?
Possibly is an adverb meaning that something might be true, possible, or likely to happen, without making a definite claim. It is commonly used to qualify information: “He is possibly the author” says that this could be the case but that the speaker lacks certainty. In practical contexts, “It may possibly rain” often sounds more tentative and qualified than a simple “it may rain,” especially in formal or careful writing. The word can also introduce an explanation, as in “The meeting was postponed, possibly because of bad weather.” Compared with probably, possibly presents fewer positive expectations and generally avoids implying that the outcome is more likely than not. It is useful when accuracy and honesty are more important than sounding decisive, though repeated use can make a statement sound uncertain or evasive.

Possibly is the language of possibility: it leaves a door open without promising what is behind it.

Where does possibly come from?
Possibly comes from the adjective possible, which derives from Latin possibilis, meaning “able to be done or happen,” from potens, meaning “able” or “capable.” The adverb was formed in English by adding the suffix -ly to possible. Related forms include possibility and impossible, which preserve the same Latin root through different English derivations.
