But I haven’t encountered enough scientific spoken American to have developed an instinct for whether or not Americans actually pronounce the ‘h’ in ‘herb-‘ words like ‘herbivore’ or ‘herbaceous’; so in this text I was a bit thrown by encountering both “a herbaceous plant”, and “an herbaceous plant”. Wondering whether this is situational pronunciation? A variation on the hyper correct ‘an precedes words that start with H if the first syllable is unstressed’ rule that gives you “an hotel” and “an historic event”? Just error?
Can anyone enlighten me?
