The Spanish word for “tell them” is “diles” — A2 level. This is a very common word in everyday Spanish.

The Power of the Command
‘Diles’ is the informal command ('tú' form) of the verb 'decir' ('di'), with the pronoun 'les' (to them/y’all) attached directly to the end.
Pronoun Placement Rule
When giving an affirmative command (telling someone to do something), any pronoun objects (like 'les') must be glued onto the end of the verb.
Di vs. Decid
The base command 'di' is only for a single informal person ('tú'). If you are talking to multiple people, you would use 'digan' (formal plural) or 'decid' (informal plural, mostly Spain).
Incorrect Pronoun Order
Mistake: “Les di.”
Correction: Diles. (When giving a command, the pronoun must follow the verb.)
Confusing 'Les' and 'Le'
Mistake: “Dile (when talking to multiple people).”
Correction: Diles. ('Dile' means 'Tell him/her/you formal'; 'Diles' means 'Tell them/you all'.)
