Imitation: The act of copying the behavior or actions of others. In terms of language development, children often imitate the speech patterns and words they hear from those around them.
Language Acquisition: The process by which individuals learn a first or second language. It involves both conscious learning (formal instruction) and unconscious learning (absorbing language through exposure).
Babbling: The stage in early language development where infants produce repetitive syllables (such as "ba-ba" or "ma-ma"). Babbling is an important precursor to actual words and helps infants practice using their vocal cords and mouth muscles.
