The Nuance Difference: "たいてい" vs "連絡する"

In Japanese, both たいてい and 連絡する are often translated to English but have distinct usages. たいてい (たいてい (taitei)) represents "usually, mostly" (Level: N5) and typically represents Adverb of frequency. Indicates something happens most of the time, but not necessarily always. Stronger than 時々 but weaker than いつも.. On the other hand, 連絡する (れんらくする (renraku suru)) translates to "to contact, to get in touch with" (Level: N4) and is used for A する-verb. Used for making contact, often via phone or email.. Mixing these up can sound unnatural to native Japanese speakers!
