An idiomatic expression meaning ‘a lot of’; it is followed by a plural noun.
que (relative pronoun)
Introduces a relative clause that describes the preceding noun.
deixam (verb agreement)
The verb must agree with the plural antecedent ‘coisas’, so the correct form is ‘deixam’.

✕Common Mistakes
Tem um monte de coisas que deixa a velocidade lenta.
The verb must agree with the plural noun ‘coisas’; use ‘deixam’ instead of the singular ‘deixa’.
Tem um monte de coisa que deixam a velocidade lenta.
‘Um monte de’ always takes a plural noun; ‘coisa’ (singular) is incorrect here.

In very formal writing you might place the adjective before the noun, but in everyday speech the post‑nominal position is preferred.

Cultural Tip
In Brazil, ‘velocidade lenta’ is most often heard in the context of internet or mobile data speed, but it can also refer to traffic jams or a sluggish computer. The phrase is informal; in a formal report you would replace ‘tem um monte de’ with ‘há muitos’ or ‘existe um grande número de’. Regional accents may affect the pronunciation of ‘monte’ (often sounding like ‘mõtʃi’ in Rio de Janeiro).
