Final Thoughts
The real power of these words shows up when you start using them. English vocabulary grows through tiny daily moments, not long study hours. Say the words out loud. Drop one into a chat. Use another in a quick sentence. When a word fits into real life, it sticks.

Think of your vocabulary like a small toolkit. Basic words get the job done, but advanced words help you express ideas with more clarity. You do not need to use them all the time. You only need the right word at the right moment.

A simple routine helps. Pick two new words each day and use them once. Connect each word to something real in your life so it feels natural. Over time, your speaking gets clearer, your writing gets sharper, and expressing your thoughts feels easier.

Small steps build fluency. One new word. One better sentence. Keep going.
