Contrae una malattia.

Contrae is the third-person singular present indicative of contrarre.

So it matches subjects like:

• lui = he
• lei = she
• esso/essa = it

Contrarre is a somewhat irregular verb. Its present tense includes forms like contraggo, contrai, contrae, contraiamo, contraete, contraggono.

Italian often leaves out subject pronouns when they are understood from the verb form.

So instead of saying Lui contrae una malattia, Italian can simply say Contrae una malattia.

In isolation, contrae could mean he contracts, she contracts, or sometimes it contracts, depending on context. In real use, the surrounding sentence usually makes the subject clear.

Yes, it is correct and natural, but it sounds fairly formal or medical.

Italian often uses contrarre with things like:

• una malattia
• un'infezione
• un virus

In everyday speech, people may prefer other expressions depending on the situation, such as ammalarsi or a more specific phrase like prendere l'influenza. So contrarre una malattia is standard, but a bit more formal than casual conversation.

Because malattia is a feminine singular noun, so its indefinite article is una.

Here una malattia means an illness / a disease, in a non-specific sense. If you were naming a specific disease, the article might be different, for example:

• contrae l'influenza
• contrae il morbillo

So una is used because the sentence refers to some illness, not a particular named one.

Malattia is a feminine singular noun.

A few useful forms:

• singular: la malattia
• plural: le malattie

So in this sentence, una malattia is simply the singular indefinite form.

It is pronounced roughly con-TRA-eh.

A key point: ae here is not pronounced like a single English-style vowel sound. The final vowels are kept separate, so contrae has three syllables: con-tra-e.

The stress falls on tra.

It is pronounced roughly ma-lat-TI-a.

Two important things:

• the tt is doubled, so it is held a little longer than a single t
• the stress is on ti

So do not flatten it into something like ma-LA-sha. Keep the ending clear: -ti-a.

It is in the present indicative.

Depending on context, that can express:

• something happening now
• a general fact
• a habitual action
• a narrative present in written style

So Contrae una malattia is present tense, not past.

A common way is Ha contratto una malattia.

That uses:

• ha = has
• contratto = past participle of contrarre

So:

• contrae = contracts / is contracting
• ha contratto = has contracted / contracted

Yes. They come from the same verb: contrarre.

• contrae = present tense
• contratto = past participle

This is useful because learners often recognize contratto first. In this sentence, though, the form is contrae, so it is definitely a present-tense verb, not a noun or past participle.

It can stand alone grammatically, but it often feels a bit context-dependent because the subject is omitted.

Without context, you know someone contracts a disease, but not exactly who. In real Italian, that is normal, because the subject is often understood from the surrounding text.

So the sentence is complete, but context would usually tell you whether it means he, she, or something else.
