Odia aspettare.

Odia is the third-person singular present tense of odiare (to hate).

So:

• io odio = I hate
• tu odi = you hate
• lui/lei odia = he/she hates

In Odia aspettare, odia means he/she hates.

Italian often leaves out subject pronouns when they are not needed. The verb ending already gives a lot of information.

So instead of saying:

• Lui odia aspettare
• Lei odia aspettare

Italian very naturally just says:

• Odia aspettare

The subject is understood from context.

Yes. Odia can mean:

• he hates
• she hates
• sometimes even it hates, depending on context
• in some cases formal you hate (Lei odia)

Italian verbs often do not show gender by themselves, so you need context to know exactly who the subject is.

After verbs like odiare, Italian commonly uses an infinitive to express the action someone hates, likes, wants, prefers, etc.

So:

• odia aspettare = hates to wait / hates waiting
• ama leggere = loves to read / loves reading
• preferisce camminare = prefers to walk

This is very similar to English.

No. You say:

• Odia aspettare

not normally:

• Odia di aspettare

With odiare, the infinitive usually comes directly after the verb with no preposition.

It can do both, depending on whether there is an object.

• aspettare = to wait
• aspettare qualcuno = to wait for someone

That is different from English, which usually needs for before an object:

• Aspetto Maria = I’m waiting for Maria

In Odia aspettare, there is no object, so it simply means to wait.

Both are natural translations.

English can express this idea in two common ways:

• hates to wait
• hates waiting

The Italian sentence covers both ideas.

Yes, absolutely.

• Odia aspettare = natural, neutral
• Lui odia aspettare = he hates waiting

Adding lui can:

• make the subject clearer
• add emphasis
• contrast with someone else

For example:

• Io non mi arrabbio, ma lui odia aspettare. = I don’t get angry, but he hates waiting.

Odia is pronounced roughly oh-DEE-ah.

A few pronunciation notes:

• it has three syllables: o-di-a
• the stress is on di: o-DI-a
• it is not pronounced like a single syllable such as oya

And aspettare is roughly ah-speht-TAH-reh, with the stress on ta.

It is grammatically present tense, but like the English present simple, it often expresses a general habit or characteristic.

So Odia aspettare usually means something like:

• waiting is something he/she hates in general
• he/she is an impatient person
• he/she does not like having to wait

Depending on context, it could also describe the present situation, but most naturally it sounds like a general statement.
