'Bolsa' is the most widely understood term for a shopping bag (plastic, paper, or reusable).
'Bolsa' is the standard term. You may hear 'bolsa de plástico' to be more specific.
'Bolsa' is the common word used in stores and everyday situations.
'Bolsa' is used, but it's extremely common to hear 'bolsita' (literally 'little bag'), even for a standard-sized grocery bag.
'Bolsa' is correct, but be careful not to say 'bolso', which means 'handbag' or 'purse'. Using 'bolso' will cause confusion.
Using 'bolso' instead of 'bolsa'. — Saying 'Necesito un bolso' means 'I need a handbag/purse'. 'Bolso' (masculine) is for carrying personal items. 'Bolsa' (feminine) is for groceries or shopping. Always use 'bolsa' at a store.
Forgetting to conjugate the verb 'necesitar'. — Saying 'Yo necesitar una bolsa' is incorrect. Verbs must change based on who is doing the action. For 'I' (Yo), the correct form is 'necesito'. The full sentence is 'Yo necesito una bolsa' or just 'Necesito una bolsa'.
Using 'saco' for a shopping bag. — Saying 'Necesito un saco' means 'I need a sack' (like a potato sack) or 'I need a blazer/jacket' in some countries. It is not the correct word for a grocery bag. Stick with 'bolsa'.
