• SynonymしばしばWrittenMeans often or repeatedly, as in 「しばしば遅刻する」. Close in sense to ちょくちょく, but it belongs to written, formal prose and is rarely heard in speech.
• SynonymたびたびNeutralMeans repeatedly or many times, as in 「度々お邪魔して」. It stresses the same thing happening over and over, works in polite set phrases, and sounds more measured than ちょくちょく.
• SynonymしきりにNeutralMeans frequently and without pause, as in 「しきりに謝る」. It stresses continuous occurrence in a short span and can also express eagerness; ちょくちょく is once every so often.
• SynonymちょいちょいCasualColloquial. Means now and then or often and is almost interchangeable with ちょくちょく; it also describes light, nimble movement or doing something with ease.
• SynonymちょこちょこCasualColloquial. Mostly describes walking with small quick steps or fidgeting restlessly. For 'now and then', as in 「ちょこちょこ顔を出す」, it is close to ちょくちょく.
• Synonym再三さいさんWrittenMeans again and again, as in 「再三注意する」. It stresses one action repeated many times and is typical of reminders and requests. A written word.
• Synonym再々さいさいWrittenMeans over and over, but it is rarely used and has a written feel; in everyday speech say 「たびたび」 or 「ちょくちょく」.
• SynonymしょっちゅうCasualMeans all the time or constantly, as in 「しょっちゅう忘れる」. The frequency is higher than ちょくちょく, and the word is colloquial.
• Synonym頻繁ひんぱんWrittenA na-adjective meaning frequent, as in 「頻繁に連絡する」. Common in descriptions and reports, it is more formal than ちょくちょく.
• SynonymしげしげWrittenMeans frequently, as in 「しげしげと通う」; it also means gazing fixedly, as in 「しげしげと眺める」 — a sense ちょくちょく lacks. A written-style word.
• SynonymしきりとWrittenSame meaning as 「しきりに」: frequently, eagerly. It sounds slightly dated and is used less; in everyday speech say 「しきりに」.
• Antonym滅多にめったにNeutralWith a negative it means rarely or seldom, as in 「滅多に来ない」 — the opposite of ちょくちょく, which suggests something happening often.

In everyday speech, use 「ちょくちょく」 or 「ちょいちょい」 for 'now and then'; when something happens more often, say 「しょっちゅう」. In written prose, prefer 「しばしば」 or 「度々」. The opposite of ちょくちょく is 「滅多に」.
