One of the primary mechanisms of vocabulary expansion is borrowing from other languages. For instance, English has borrowed extensively from French, Latin, and Greek, enriching its lexicon with words like "entrepreneur," "alibi," and "phenomenon." Similarly, the coining of new terms, often in response to technological or scientific developments, continually adds to our linguistic repertoire. Words like "selfie," "blog," and "cryptocurrency" are recent additions that reflect our changing digital landscape.
