Hi
Can I say "... driving on a field road"? (a non-asphalted road)
Agree with Gillnetter and add that there are regional colloquialisms for roads. Where I come from- rural Midwestern US- unpaved public roads are called 'dirt roads' or 'gravel roads'. There are very few dirt roads still in existence.
A private passage for a farmer's individual use as Gillnetter describes would be called a 'lane' where I come from. A gravel or dirt public road so seldom used that grass is growing between two bare strips might be called a 'double track' in describing it, but still refered to as a 'road'. A two-lane, asphalt-paved rural public road is called a 'blacktop'. The same description paved with concrete is called a 'hardroad'.
I've never heard the term 'field road', though I repeat- there are regional and national variations.
I'm familiar with "blacktop" as a description of a road's surface, but not to be used to name a road. Never heard any road called a "hardroad."
Re-hi,
Dirt road is not kind of pejorative? And what about "land road"?
"Dirt road" is common for me. Or even simply "unpaved road."
"Land road" doesn't make any sense to me at all.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
