Nuance Contrast & Social Differences

In Japanese, both よく and 眠い are often translated to English but have distinct usages. よく (よく (yoku)) represents "well, often, frequently" (Level: N5) and typically represents Adverb. Can mean 'well'. On the other hand, 眠い (ねむい (nemui)) translates to "sleepy" (Level: N4) and is used for I-adjective. Describes the feeling of wanting to sleep. It is not a verb for 'to sleep'.. Mixing these up can sound unnatural to native Japanese speakers!
