💡 Grammar Points
Verb + Pronoun Together
In Spanish, when the verb is in its base form (infinitive) or the 'ing' form (gerund), the little words like 'lo' (it/him) stick right onto the end of the verb, making a single word like 'mantenerlo'.
Stress Moves
When you attach the pronoun, the stress in the word often shifts. 'Mantener' is stressed on the last syllable, but 'mantenerlo' needs an accent mark (mantenerlo) if it were written to keep the stress where it belongs, though often this rule is flexible in spoken Spanish.
❌ Common Pitfalls
Placing 'lo' separately
Mistake: "Quiero lo mantener."
Correction: Quiero mantenerlo. (When you have two verbs, the pronoun either goes before the first verb or attached to the second one.)
⭐ Usage Tips
Remember the 'Lo'
'Lo' always refers to a masculine singular thing or a general idea. If you were talking about a feminine thing (like 'la casa'), you would say 'mantenerla'.

Mantenerlo (to support him) can refer to physical support, such as helping someone overcome a difficult step.

Frequently Asked Questions
Why is 'mantenerlo' one word instead of two?
When the main verb is in its base form (infinitive), the little object pronouns like 'lo' (it/him) must attach directly to the end of the verb, forming a single, longer word.
Can I use 'mantener' with other pronouns, like 'la' or 'los'?
Absolutely! If you are talking about keeping a feminine thing (like 'la promesa'), you would say 'mantenerla.' If you are keeping several things, you would use 'mantenerlos' or 'mantenerlas.'
