Jedna štipaljka je pala s užeta, pa je baka uzela drugu.

Because štipaljka is a feminine noun, so the number one must also be in the feminine form.

• masculine: jedan
• feminine: jedna
• neuter: jedno

So:

• jedna štipaljka = one clothespin / one peg

In this sentence, jedna can also feel a bit like one particular or a single clothespin.

Štipaljka is in the nominative singular because it is the subject of the first clause — it is the thing that fell.

Structure:

• Jedna štipaljka = the subject
• je pala = fell

So the basic pattern is:

• subject + verb

This is the past tense in Croatian.

Croatian past tense is usually made with:

• the auxiliary biti in the present tense
• plus the past participle

Here:

• je = is/has helper form, used for he/she/it in the past tense
• pala = past participle of pasti = to fall

So je pala means fell / has fallen.

Also, pala is feminine singular, because it agrees with štipaljka, which is feminine.

Compare:

• on je pao = he fell
• ona je pala = she fell
• ono je palo = it fell

Because Croatian does not follow English natural gender in the same way. Croatian nouns have grammatical gender.

The noun štipaljka is grammatically feminine, so anything that agrees with it must also be feminine:

• jedna
• pala

Even though in English you might refer to a clothespin as it, in Croatian the grammar still treats štipaljka as feminine.

Here s means from or off.

So:

• pasti s + genitive = to fall from / off

That is why we get:

• s užeta = from the line / off the rope

The noun uže means rope / line, and after s in this meaning, it goes into the genitive.

So:

• dictionary form: uže
• genitive singular: užeta

Both s and sa can mean the same thing here, but sa is usually used for easier pronunciation before certain sound combinations.

Here, s užeta is perfectly natural and standard.

Very roughly:

• s = normal shorter form
• sa = often used when pronunciation would otherwise be awkward

So Croatian speakers say:

• s užeta
• but often sa stola, sa mnom, etc.

Užeta is genitive singular.

Its dictionary form is:

• uže = rope, clothesline, cord

Why genitive?

Because with the meaning from/off, the preposition s takes the genitive:

• s užeta
• sa stola
• s police

So in this sentence:

• uže → užeta

Because Croatian has a strong tendency for clitics like je to come in the second position of a clause.

So after pa, the auxiliary je comes very early:

• pa je baka uzela drugu

This is very natural Croatian word order.

You may also see word order shifts in Croatian for style or emphasis, but placing je in second position is extremely common.

Uzela is the past participle of uzeti = to take.

It is feminine singular because the subject is baka, and baka is feminine.

So:

• baka je uzela = grandmother took

Compare:

• djed je uzeo = grandfather took
• baka je uzela = grandmother took

Because drugu is the accusative feminine singular form, and it is the direct object of uzela.

The verb uzeti takes a direct object:

• took what? → drugu

Since the implied noun is feminine (štipaljku), the adjective/pronoun must also be feminine accusative singular:

• nominative: druga
• accusative: drugu

You can think of the full form as:

• baka je uzela drugu štipaljku

But Croatian often leaves out the noun when it is obvious from context.

Here it most naturally means another one or a different one.

Since one clothespin fell, grandmother took another clothespin.

In context, drugu can sometimes also feel like the other one, but here the idea is simply replacement: she took a different clothespin.

So the hidden full phrase is:

• drugu štipaljku = another / a different clothespin

Because Croatian normally has no articles.

English says:

• a clothespin
• the clothespin

Croatian usually just says:

• štipaljka

If needed, Croatian shows definiteness or indefiniteness through:

• context
• word order
• demonstratives such as ta, ova, ona
• numerals such as jedna

So jedna štipaljka can sometimes help give the sense of one or a certain one, but Croatian still does not have a true article system like English.

Pa links the two clauses and here means something like:

• so
• then
• and so

The idea is:

• one clothespin fell off the line,
• so grandmother took another one.

It often introduces the next event or consequence in a very natural, conversational way. It is extremely common in Croatian.
