Foggy is an adjective . No ?

Question

Surely " foggy" is an adjective . The noun is " fog" !  So why not use "está "  for " it is foggy "  _

Answer

There are specific rules on talking about weather in Spanish. You can only say hay niebla.See lesson - using hay and estar to talk about weather.

Answer

niebla is a noun. Nublado would the adjective. I don't see any problems in "está nublado".

Answer

Hola BrianWhen we say that we use a noun with hay and an adjective with está, we mean these are nouns and adjectives in Spanish, not necessarily in English.Hay niebla Hay + noun niebla The translation in English for this is a bit different and you use an adjective, not a noun: it is foggy (foggy is an adjective) - Literally what we say here in Spanish is "There is fog", but that would sound terrible in English.SaludosInma
