“Become” is the verb for changing into a new state, role, or condition. It often describes a process or result of change, not a deliberate action like “make.” In this module, you learn how “become” works across present, past, and past participle forms: become, became, become.

Use “become” for the present and future with most subjects, and “becomes” with he, she, and it. It describes what is happening over time, what is generally true, or what will happen. It is commonly followed by an adjective, a noun, or an expression of status.

“Become” is commonly followed by an adjective to describe a new state, or a noun phrase to describe a new identity or role. It can also be followed by expressions like “a problem,” “a habit,” or “a tradition” to show something developing into a recognized thing. The focus is on the end state after change.

Choose the form by the time relationship you want. “Become” is for present or general truths, “became” is for a completed past change, and “have or has become” connects a past change to now or emphasizes the result now. This helps you express whether the change is finished in the past or still relevant.

“Become” has stress on the second syllable. “Became” also stresses the second syllable, with a long vowel sound in that syllable. Keep the first syllable reduced in casual speech so the stress pattern stays clear and natural.

“Become, became, become” are the base form, simple past, and past participle of the same verb of change. Use “become” for present or general change, “became” for completed past change, and “have or has become” to connect a past change to the present. Use “become” when you want to emphasize transition rather than a simple state.
