Usage notes

• If a lo mejor is used with a clause, the verb in that clause is used almost exclusively in the indicative form:

A lo mejor Álex no sabe hablar inglés. ― Maybe Alex doesn't know how to speak English.Category:Spanish terms with usage examples#A%20LO%20MEJOR

Nos falta la leche a lo mejor. ― We are out of milk, possibly.Category:Spanish terms with usage examples#A%20LO%20MEJOR

The use of the subjunctive mood in these verbs, while rare, is also considered valid, but only when the verb comes after a lo mejor in the sentence. (Thus, in the above examples, A lo mejor Álex no sepa hablar inglés is valid, but *Nos falte la leche a lo mejor is not.)

• By contrast, the synonyms of a lo mejor, such as quizás or tal vez, usually do trigger the use of the subjunctive mood (see quizásCategory:Spanish links with redundant alt parameters#A%20LO%20MEJORCategory:Spanish links with manual fragments#A%20LO%20MEJOR).
