Définit article (La)
‘La’ is the feminine singular definite article, agreeing with the feminine noun ‘déco’.
Déco (abbreviation)
‘Déco’ is the colloquial short form of ‘décoration’; it is feminine, so adjectives and articles must agree.
Devoir (doit)
‘Doit’ is the third‑person singular present of the modal verb ‘devoir’, expressing obligation or necessity.
Coller (infinitive)
Literally ‘to stick’, ‘coller’ is used figuratively to mean ‘to match’ or ‘to fit well with’.
Au = à + le
The preposition ‘à’ contracts with the masculine singular article ‘le’ to form ‘au’, meaning ‘to the/with the’.
Thème (masc.)
‘Thème’ is a masculine noun; the article ‘le’ is hidden in the contraction ‘au’.

✕Common Mistakes
La déco doit coller au le thème.
‘Au’ already includes the article ‘le’; adding another ‘le’ is redundant.
La déco doit coller le thème.
The verb ‘coller’ needs the preposition ‘à’ (contracted to ‘au’) to indicate what it sticks to.
La déco doit être collé au thème.
‘Collé’ is the past participle used in a passive construction, which changes the meaning to ‘must be glued to the theme’. Use the infinitive ‘coller’ instead.
↔Alternatives

Cultural Tip
In French, ‘coller’ is often used figuratively to talk about style or ideas that ‘fit together’ (e.g., ‘ça ne colle pas’ = ‘that doesn’t fit/doesn’t make sense’). ‘Déco’ is informal; in a formal written report you would use ‘décoration’. Also, French speakers tend to be very precise about colour palettes and textures when they say something must ‘coller au thème’, so be ready to discuss specifics.
