いつも
いつも · itsumo · JLPT N5 · adverb
always
itsu (when) + mo (even/any) = whenever at all, so: always
いつ means when, and も adds the sense of any or every. Any-when becomes always. The same pattern builds だれも (anyone/no one) and どこも (everywhere/nowhere), which is why いつも flips to never with a negative verb.
