Learn Turkish: Onun karakteri bence çok güçlü. - His character is very strong in my opinion.

Bence is made of the pronoun ben (I/me) and the suffix -ce. This suffix is used to show perspective or point of view, so adding it to ben literally means "according to me" or "in my opinion." You can also use it with other pronouns, like sence (in your opinion).

Why is there an -i at the end of karakteri?

It's the 3rd person possessive suffix, matching the pronoun Onun (his/her). In Turkish, when you say "his character", you must mark both the owner (Onun) and the thing being owned (karakter-i).

How does the word güçlü get its meaning?

It comes from the noun güç, which means "strength" or "power." By adding the suffix -lü (which means "with" or "having"), it turns into the adjective güçlü, literally meaning "having strength" or "strong."

Can I put bence at the beginning of the sentence?

Yes! Turkish word order is quite flexible. You can easily say Bence onun karakteri çok güçlü. Placing bence in the middle, as it is in this sentence, just slightly shifts the flow of the sentence, but the meaning stays exactly the same.
