Talón vs. tacón
The Spanish language, like many others, has words that sound or look alike but carry different meanings. Two such examples are 'talón' and 'tacón', which both roughly translate into 'heel' in one form or another.
Talón
This word refers to the back part of a person's foot. It is the area below the ankle where the foot makes contact with the ground.
Me duele el talón después de correr.
(My heel hurts after running.)
El zapato de Antonio está roto en el talón.
(Antonio's shoe is broken at the heel.)
Tacón
In contrast, 'tacón' specifically refers to the raised part at the back of a shoe which helps to elevate the wearer's heel. It does not refer to any part of the human body itself.
Ella siempre usa zapatos de tacón alto para parecer más alta.
(She always wears high heels to appear taller.)
Estoy buscando un par de botas sin tacón.
(I am looking for a pair of boots without a heel.)
Summary
'Talón' and 'tacón' both have similar English translations ('heel'), but are used in different contexts within Spanish. While 'talón' refers specifically to the body part found under the ankle, 'tacón' refers to the component of a shoe that raises the heel off the ground. Understanding these nuances is key to fluent Spanish comprehension and conversation.
