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

Como similes: the noun is fixed
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.
| English | Fixed | Not 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
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.
| Means | Spanish | English 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 |
mule
bull
goat
tortoise
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
The other half are comparisons: + adjective + + a fixed noun. Literally "more X than the bread":
| Means | Spanish | Literally |
|---|---|---|
| very kind | | better than bread |
| obvious | | clearer than water |
| very sharp | | sharper than hunger |
| ancient | Matusalén | older than Methuselah |
| very ugly | Picio | uglier 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
Each simile keeps the verb its adjective takes: for character, for a state, for a sudden change.
| Verb | Spanish | English |
|---|---|---|
. | 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:
| Name | Who | Simile |
|---|---|---|
| Matusalén | Methuselah, who lived 969 years (Genesis) | Matusalén |
| Magdalena | Mary Magdalene, weeping in the Gospels | Magdalena |
| Picio | a 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.
