"The neighbors have adopted a tiny dog."

Translation: Les voisins ont adopté un chien minuscule.

[Bethan680445]

Why is miniscule (size) not one of the adjectives that goea before the noun?

[Jojo553168]

Un minuscule chien would be possible, but would not sound more natural. Not every adjective follows the rule you mention, which actually is not a rule, but rather a memory trick for french learners.

it confuses me also. I was just marked wrong for saying "the biggest room" as "la chambre plus grande" - correct answer is "la plus grande chambre"; and here I was marked wrong to say "a tiny dog" as "un minuscule chien". Don't French have a general rule?

[Geoff_Campbell]

Nope - pas du tout!

[Sal956085]

So then only was is by knowing and remembering when it should be used and when it shouldn't?

[Antti546484]

Feminine form "Les voisines ont adopté un chien minuscule" was accepted.

[dominique.dom3]

les voisins ont adopté un minuscule chien se dit aussi en francais.....

[tigerstef]

Les voisins, ils ont adopté un chien miniscule - word selection doesn't include the comma, would the be correct though? It was marked wrong.
