Synonym of BEGIN.

**The reasoning** A **synonym** is a word that has the same or nearly the same meaning as another word. "Begin" means to start something, to commence, or to initiate an action. When you "begin" reading, you're starting to read. When you "begin" cooking, you're starting to cook. So the word that means exactly the same thing is **"Start"** — they're interchangeable in most sentences. **Why the wrong options tempt you** Options A, C, and D (End, Stop, Finish) are all **antonyms** — words that mean the *opposite* of begin. This is a classic exam trick! They're testing if you know the difference between synonyms (same meaning) and antonyms (opposite meaning). Students rushing through might pick "End" thinking about word pairs, but that's the trap. **Quick takeaway** Synonyms = Same meaning, Antonyms = Opposite meaning. "Begin" and "Start" both mean to kick something off, while End/Stop/Finish mean to wrap it up — always check what the question is actually asking for!
