Spanish Similes: dormir como un tronco, terco como una mula

By Michael McGettrick and Sergio Linares-HernandesUpdated 12 October 2026

Spanish often swaps a plain adjective for a fixed comparison, and the noun in it never changes:

Como similes: the noun is fixed

masculinefemininethe fixed nounWhat do the colours mean?

Half the similes are an adjective or a verb plus and a noun. The noun is welded on: swap it and the phrase stops being Spanish.

EnglishFixedNot said
strong as an ox
sleep like a log
red as a beetroot

A few similes have one accepted variant, fixed in its turn: lirón (like a dormouse, which hibernates) means much the same as , with a hint of sleeping long.

The adjective still agrees with the person; the noun stays exactly as it is:

  • . - My father is as stubborn as a mule.
  • . - My mother is as stubborn as a mule.
  • tapia. - My grandmother is as deaf as a post.

Animals in Spanish similes

masculinefemininethe fixed nounWhat do the colours mean?

Most animal similes come from village life: the mule that refuses to move, the bull's strength, the goat that climbs where it should not.

MeansSpanishEnglish twin
work very hard work like a dog
very slow slow as a snail
eat a lot eat like a horse
be crazy be mad as a hatter
  • mulemule
  • bullbull
  • goatgoat
  • tortoisetortoise

The in is not the fruit but a file, which wears away whatever it touches:

  • . - My brother eats like a horse.
  • . - That boy is completely mad.

Más ... que similes

masculinefemininethe fixed nounWhat do the colours mean?

The other half are comparisons: + adjective + + a fixed noun. Literally "more X than the bread":

MeansSpanishLiterally
very kind better than bread
obvious clearer than water
very sharp sharper than hunger
ancient Matusalénolder than Methuselah
very ugly Piciouglier than Picio
very tiresome heavier than a cow in your arms

The adjective agrees here too:

  • . - My neighbour is as good as gold.
  • . - It's crystal clear.

Learn the frame with the noun. The usual form is pan, with and ; is usually said with , though is heard too.

Ser, estar or ponerse

masculinefemininethe fixed nounWhat do the colours mean?

Each simile keeps the verb its adjective takes: for character, for a state, for a sudden change.

VerbSpanishEnglish
.He's as stubborn as a mule.
.He/she is crazy.
tapia.He's as deaf as a post.
.He went as red as a beetroot.

Where the images come from

Some similes lean on stories every Spanish speaker knows:

NameWhoSimile
MatusalénMethuselah, who lived 969 years (Genesis) Matusalén
MagdalenaMary Magdalene, weeping in the Gospels Magdalena
Picioa 19th-century man from (legend) Picio

Others simply paint a picture. A flan, the wobbly set custard, shakes at a touch, so flan is to shake with nerves. A tapia is an old wall of packed earth: about as attentive as a deaf ear.

  • flan. - Before the exam I was shaking like a leaf.

Frequently asked questions

What is a fixed simile in Spanish?
A set comparison that stands in for a plain adjective: (like) plus a noun, or plus an adjective plus and a noun. Instead of you say (stubborn as a mule); instead of , (good as gold). Every speaker knows them, and they work like English deaf as a post or happy as Larry.
Can you change the noun in a Spanish fixed simile?
No. You are (a bull) or, in another fixed variant, roble (an oak), never , and you sleep (a log). A few similes have an accepted variant, such as lirón (a dormouse), but the variants are fixed too. The adjective does agree: for a man, for a woman, and the stays.
Why does Spanish compare a stubborn person to a mule?
The images come from a rural past. The mule was the working animal every village knew, famous for refusing to move, so is a farmer's observation frozen into speech. The same animal, worked all day, gives (to work very hard). The bull gives , the strength of a fighting bull.
Are Spanish similes used in conversation or in writing?
Mostly in conversation. (to be crazy) is something you say to a friend over coffee, not in a work email. A few, like (crystal clear) and (white as snow), are enough for writing.
What does ?
It depends on the verb. , with , means he is as good as gold: kind, gentle. , with , is colloquial for he is very good-looking, because said of a person means attractive. Pick the verb carefully.
