What does it mean when "te" or "se" is added onto a verb in infinitive form.

I've been trying to find an article online for this but no luck! Im so confusedd.

Specific examples will make it clearer!

te = could be reflexive pronoun (yourself), direct object (you), indirect object = (to/for/at/from you ) all singular and femini ne.

se = could be reflexive pronoun (self, himself, herself, yourself (formal), themselves, yourselves (formal, plural) It could also be standing in for the indirect-object pronouns "le" or "les" when followed by lo, la, los, or las.

Once again, give me the examples you are looking at and I tell you exactly what it is!
