• Antonym滅多にめったにNeutralThe opposite: with a negative, 'rarely, seldom', against the frequency 「常々」 expresses.

For everyday speech, 「いつも」 is the default; in written or formal prose use 「常に」. 「常々」 itself is mostly for one's habitual thoughts and words. When the point is sheer frequency, choose 「しょっちゅう」; when it is unbroken continuity, choose 「絶えず」. The year-round words 「年中」 and 「年がら年中」 and the nonstop expressions 「のべつ」 and 「四六時中」 add shades of annoyance or exaggeration, while 「偶に」 and 「滅多に」 are the opposites.
