Recently, a proofreader suggested an edit for my story:
laughterlaugh escaped my throat.
The New Oxford American Dictionary suggests:
the action or sound of laughing:
he roared with laughter
1 an act of laughing:
she gave a loud, silly laugh
Following the definitions it would seem as if the correction goes in the opposite side here. What's the difference in usage between the nouns laugh and laughter? Are there some subtle differences in connotations, associations, undertones, usage patterns I failed to notice?
