About

いつも is an adverb that is often translated as "always".

いつも is formed by combining the も particle with いつ ("when"). As with other interrogative + も patterns (e.g. 誰だれも, どこも...), いつも can mean both "always", or "never", depending on context: if it is paired with a negative verb, いつも means "never", if it is paired with an affirmative verb, いつも means "always".
