To describe hair and eyes in Basque, you don’t use izan (“to be”) like in Spanish (“I am dark-haired”), but rather ukan (“to have”): I have black hair, I have blue eyes.
Hair: ile
The word for “hair” is ile (with the article: ilea). Adjectives come after it, and only the last one takes the -a ending:
Euskera
English
ile beltza
black hair
ile horia
blond hair
ile zuria
white / gray hair
ile gorria
red hair
ile urdina
gray hair
ile motza
short hair
ile luzea
long hair
ile lisoa
straight hair
ile kizkurra
curly hair
In Basque, hair is treated as singular, just like in Spanish. That’s why you use dut / du (not ditut / ditu).
Ile beltza eta luzea dut. — I have black and long hair.
Maialenek ile kizkurra du. — Maialen has curly hair.
Eyes: begiak
Unlike hair, “eyes” is plural (begiak). Therefore, the adjectives are also plural (-ak) and you use ditut / ditu:
Euskera
English
begi urdinak
blue eyes
begi marroiak
brown eyes
begi berdeak
green eyes
begi beltzak
black eyes
begi argiak
light eyes
begi ilunak
dark eyes
Begi urdinak ditut. — I have blue eyes.
Mikelek begi marroiak ditu. — Mikel has brown eyes.
Other features: the -dun suffix
To say “who has X” or “with X”, Basque has a very productive suffix: -duna (singular) / -dunak (plural). It’s added to a noun, and the person becomes “the one with glasses”, “the one with the beard”…
Euskera
English
betaurrekoduna
with glasses / the one with glasses
bizarduna
with a beard
biboteduna
with a mustache
burusoila
bald (literally “peeled head”)
These ones do go with izan, because they describe a quality, like an adjective:
Hura biboteduna da. — He has a mustache.
Nire aitona burusoila da. — My grandfather is bald.
Putting it all together
A typical description mixes several structures:
Maialen txikia eta argala da. Ile gorria eta kizkurra du. Begi berdeak ditu. Betaurrekoduna da.
Maialen is short and thin. She has red and curly hair. She has green eyes. She wears glasses.
Notice how it’s divided: izan for general qualities (txikia da), ukan for hair/eyes (ile … du, begi … ditu), and -dun-a again with izan for accessories.
