Questions & Answers about Mi colega acababa de intercambiar dos teclas en el teclado.
Why is acabar in the imperfect tense (acababa) here instead of the preterite (acabó)?
The phrase acabar de + infinitive is almost always used in either the present or the imperfect tense. In the present (acaba de intercambiar), it means "has just swapped". In the imperfect (acababa de intercambiar), it sets the background for a past event, meaning "had just swapped". Using the preterite (acabó de...) would literally mean "finished swapping," which loses the idiomatic "had just" meaning.
Why use intercambiar instead of just cambiar?
intercambiar specifically means "to swap" or "to exchange" things with each other (like switching the position of two keys). cambiar is broader and usually means "to change" or "to replace". If the colleague simply put entirely new keys on the board, you would use cambiar.
I learned that "key" is llave. Why is tecla used here?
In Spanish, a key to unlock a door is a llave. However, a key on a computer keyboard, typewriter, or musical instrument (like a piano) is a tecla. Naturally, a collection of these makes up the teclado (keyboard).
Is colega a masculine or feminine noun?
It can be both! colega is an invariable noun that ends in "-a" regardless of the person's gender. You would say el colega for a male colleague and la colega for a female one. Because this sentence uses the gender-neutral possessive mi, we actually can't tell the colleague's gender from this sentence alone.
