嘆
"Ah!" is an interjection.
When you write a sentence, it normally starts with an upper-case letter and ends in a period (.), an exclamation mark (!) or an interrogation mark (?).
In English there are eight main parts of speech: noun, verb, adjective, adverb, pronoun, preposition, conjunction and finally interjection.
We could not help admiring the beautiful sunset.
She did nothing but grieve over her husband's death.
She is dying of grief.
She was distracted by grief.
She pleaded with him not to disturb her.
She has grieved over his loss for nearly ten years.
Her cleverness often amazes me.

The search results are provided by the wonderful Jisho API which itself uses various data sources which you can find on the jisho's website.
