Translation: This is a willow, not an oak.

Your comment remember me a joke in Spanish. I will try to translate it into English:

In a chemist's
Customer: Excuse-me could you give me a box of acetylsalicylic acid pills, please?
Chemist: Do you mean a box of aspirins?
Customer: Yes, exactly. Sorry I can never remember that difficult word.

And what is the mnemonic for 'acetylsalicylic acid' then? Not a medic student XP

that it is the extract from the willow tree. Nowadays synthesized and called acetylsalicylic acid (Aspirin). Comes from the latin word salix = willow tree
