cojer

A spelling error, not a legitimate variant — the correct form is always coger, with g. The confusion arises because g and j sound identical before e and i, but the RAE is explicit that cojer does not exist as a word in Spanish (except in the naturally j-spelled forms cojo, coja, cojas, cojamos, cojan).

• "Voy a cojer el libro" es un error; debe escribirse "voy a coger el libro." — "Voy a cojer el libro" is a mistake; it should be written "voy a coger el libro."
• Mucha gente escribe cojer por error debido a que suena igual que coger. — Many people write 'cojer' by mistake because it sounds identical to 'coger.'
• Solo las formas yo cojo, que yo coja, etc., llevan j; el infinitivo siempre es coger. — Only the forms 'yo cojo,' 'que yo coja,' etc., take a j; the infinitive is always 'coger.'

This isn't a stylistic choice or regional variant — writing cojer for the infinitive is simply incorrect; always write coger, reserving the j for the specific conjugated forms where it's required.
