Predicting Gender with -ismo
Most words ending in '-ismo' (like 'capitalismo', 'optimismo', or 'terrorismo') are masculine. This is a reliable pattern you can use to guess the gender of many abstract concepts.
Don't forget the 'El'
Mistake: “Hablamos sobre terrorismo.”
Correction: Hablamos sobre EL terrorismo. In Spanish, when talking about general concepts or 'isms', we usually need to put 'the' (el/la) in front of the word, even if we don't do that in English.
