How to Say "flank" in Spanish
The most common Spanish word for “flank” is “lado” — use 'lado' when referring to a general side, whether it's a physical location like a street or a more abstract side of a formation or an animal.
lado
la-dohˈla.ðo
Examples

The left side of my body hurts.
Escribe tu nombre en un lado del papel.

Always Masculine
'Lado' is always a masculine word, so you'll always say 'el lado' or 'un lado', never 'la' or 'una'.
Using 'Lado' for Clothing
Mistake: “Me gusta esta lada de la camisa.”
Correction: Me gusta este lado de la camisa. Remember, 'lado' is always masculine, even when talking about something that is feminine, like 'la camisa'.
costado
kos-TAH-dohkosˈtaðo
Examples

My side hurts after running so much.

Use of the Definite Article
When talking about body parts, Spanish often uses 'el' or 'la' (the) instead of 'mi' or 'tu' (my or your), as in 'Me duele el costado' (My side hurts).
Confusing Costado and Lado
Mistake: “Using 'lado' when referring specifically to the ribcage area or flank of a person/animal.”
Correction: 'Costado' is usually better for the physical side of the body, while 'lado' is for directions or general sides (like the left side of the room).

Masculine Noun
This word is always masculine, even if the 'side' refers to something feminine like 'la montaña' (the mountain).
Pluralization
Simply add an 's' to make it plural (los flancos) when talking about multiple sides.
Prepositions with Flanco
We usually use 'por el' (by the/through the) to describe movement along a flank.
Flanco vs. Lado
Mistake: “Using 'flanco' for everyday small objects.”
Correction: Use 'lado' for things like a phone or a table. Use 'flanco' for bigger things like mountains or large ships.
