Learn Turkish: Gözü şişmiş ve vücudu kabarmış olabilir. - His eye might have swollen and his body might have broken out.

This sentence uses the structure for past possibility: Verb + -mIş + olabilir ("might have [verb]"). When you have multiple verbs in this structure connected by ve (and), you can drop the auxiliary verb on the first one to avoid repetition. Olabilir at the end automatically applies to şişmiş as well.

How does the word vücudu break down?

The root word is vücut (body). To say "his body", we add the 3rd person possessive suffix -u. When a vowel suffix is added, the hard consonant t at the end of vücut softens to a d (consonant mutation), resulting in vücudu.

Kabarmak often means "to rise" or "to swell". Why is it translated as "broken out" here?

While kabarmak is used for things like dough rising, when it is used to talk about skin or the body (vücut), it specifically refers to developing a raised rash, hives, or blisters. In English, we naturally translate this physical reaction as "breaking out".

Both gözü and vücudu end in a vowel. Are they in the accusative case (direct objects) here?
