Il doppio fondo contiene un nascondiglio.

Doppio fondo is a fixed expression that literally means double bottom. In practice, it usually refers to a false bottom in a suitcase, drawer, box, or similar object.

So in Italian, il doppio fondo is often understood as a hidden lower layer or concealed compartment area.

Italian uses il before most masculine singular nouns.

You use lo only before certain sounds, such as:

• z
• s + consonant
• gn
• ps
• x
• y

Since doppio begins with a normal d sound, the correct article is il:

• il doppio fondo

Because doppio is functioning like an adjective modifying fondo.

• fondo = bottom
• doppio = double

So doppio fondo works like double bottom in English: adjective + noun, with no extra word needed.

Italian often forms expressions this way:

• porta blindata = armored door / security door
• camera singola = single room
• doppio fondo = false bottom / double bottom

Contiene is the third person singular of the verb contenere, which means to contain.

So:

• io contengo = I contain
• tu contieni = you contain
• lui/lei contiene = he/she/it contains

In this sentence, the subject is il doppio fondo, which is singular, so Italian uses contiene:

• Il doppio fondo contiene... = The false bottom contains...

Un is the masculine singular indefinite article, meaning a or an.

So:

• un nascondiglio = a hiding place
• il nascondiglio = the hiding place

The sentence presents it as an unspecified hiding place, so un is the natural choice.

Yes, nascondiglio is a masculine singular noun.

Its forms are:

• singular: il nascondiglio
• plural: i nascondigli

Examples:

• un nascondiglio segreto = a secret hiding place
• molti nascondigli = many hiding places

Its basic meaning is hiding place.

Depending on context, it can also feel like:

• hideout
• secret place
• concealed compartment

In this sentence, because of doppio fondo, English might naturally translate it as secret compartment or hidden compartment, even though the literal noun is hiding place.

Yes. The basic structure is very straightforward:

• Il doppio fondo = subject
• contiene = verb
• un nascondiglio = object

So it follows the common subject + verb + object order, just like English:

• The false bottom contains a hiding place.

Yes, but the nuance changes a little.

• contiene = contains
• ha = has

So:

• Il doppio fondo contiene un nascondiglio sounds a bit more literal or descriptive.
• Il doppio fondo ha un nascondiglio is possible, but can sound less precise.
• Very often, Italian might express the idea differently depending on context, for example:
  • C'è un nascondiglio nel doppio fondo = There is a hiding place in the false bottom.
  • Il doppio fondo nasconde qualcosa = The false bottom hides something.

So the original sentence is grammatically correct, but other phrasings may sound more natural in some situations.

A simple pronunciation guide:

• doppio fondo ≈ DOHP-pyoh FOHN-doh
• nascondiglio ≈ nah-skohn-DEEL-lyoh

A few helpful notes:

• pp in doppio is pronounced more strongly than a single p
• gli in nascondiglio is a special Italian sound, similar to the lli in some pronunciations of million, but more distinctly Italian
• the stress is on:
  • dòp-pio
  • fón-do
  • nas-con-dì-glio

It is usually literal, especially for physical objects like:

• suitcases
• drawers
• bags
• boxes

It normally refers to a real false bottom or concealed layer. It is much less commonly used figuratively than some comparable English expressions.

So in this sentence, learners should first understand it as a concrete, physical thing.
