Non dubito quin avia tunicam laceram sine mora consuere possit.

After a negative expression like non dubito, Latin very often uses quin plus the subjunctive to mean that.

So:

• non dubito quin ... possit = I do not doubt that ... can ...

This is a standard Latin idiom. A learner may expect a simple that-clause like in English, but Latin often prefers quin in this pattern.

Because quin normally introduces a subjunctive clause in this construction.

So the pattern is:

• non dubito quin
  • subjunctive

That is why Latin says possit, not potest.

Possit is the present subjunctive, third person singular, from possum.

The sentence breaks down like this:

• Non dubito = main clause
• quin avia tunicam laceram sine mora consuere possit = subordinate clause introduced by quin

Inside the quin-clause:

• avia = subject
• tunicam laceram = direct object
• sine mora = adverbial phrase
• consuere = infinitive
• possit = finite verb

So the core idea is:

• I do not doubt
• that grandmother can sew up the torn tunic without delay

Because avia is the subject of possit.

A native English speaker may notice the infinitive consuere and wonder whether this should work like an accusative-and-infinitive construction. But this is not indirect statement. The finite verb in the clause is possit, and avia is its subject, so it stays in the nominative:

• avia ... possit = grandmother can / may be able to ...

If this were an accusative-and-infinitive construction, the grammar would look different.

Because laceram is an adjective agreeing with tunicam.

Both are:

• feminine
• singular
• accusative

So:

• tunicam = tunic
• laceram = torn

Together they mean a torn tunic or the torn tunic.

Latin adjectives must agree with the nouns they describe in gender, number, and case.

Latin has no articles. It does not have separate words that directly correspond to English the or a/an.

So tunicam laceram can mean:

• a torn tunic
• the torn tunic

The exact choice in English depends on context.

That is very normal in Latin and something English speakers have to get used to.

Consuere is the present active infinitive of consuo, meaning to sew together, to stitch up, or to mend by sewing.

So here it depends on possit:

• consuere possit = can sew up / may be able to mend

The infinitive expresses the action, while possit gives the idea of ability.

This is the same basic idea as English can sew.

• possit = can / may be able to
• consuere = sew up, mend

Together:

• consuere possit = can sew up

Latin often uses possum + infinitive exactly the way English uses can + base verb.

Sine is a preposition meaning without, and it takes the ablative case.

So:

• sine = without
• mora = ablative singular of mora, meaning delay

Together:

• sine mora = without delay, at once, immediately

This phrase functions adverbially, describing how the action would be done.

Latin word order is much freer than English word order, because the endings show the grammatical relationships.

This sentence is perfectly natural, but many other orders would still make sense as long as the forms stay the same.

For example, Latin can move words around to emphasize different parts of the sentence. Here, the order is fairly straightforward:

• avia appears early as the subject of the subordinate clause
• tunicam laceram stays together as a noun phrase
• sine mora comes before the infinitive
• possit stands at the end, which is very common in Latin subordinate clauses

So the order is meaningful and natural, but not rigid in the way English word order usually is.
