The Map of Longing
Lucy's final letters leave Greta in uncharted territory with Will, but give her the courage to embrace life — starting with a trip close to her heart.

Very common in everyday speech. Can refer to physical exhaustion or emotional wreckage. The literal words ('made of dust') give no clue to this meaning.
Widely used to mean doing something with full energy or living life to the fullest. Can also mean 'packed' when describing a crowded place.
Literally means to crush or grind. When used about people it means to wear them down or come down hard on them. Non-compositional in this emotional sense.
'Coña' on its own means a joke or tease, but 'ni de coña' is a fixed emphatic refusal. Slightly crude in tone but used very broadly in casual conversation.
Used when someone says or does something that strikes an emotional nerve. Affectionate or teasing in lighter moments, pointed in arguments.
