In an emotional manner; displaying emotion.
"She spoke emotionally about her loss, unable to hold back her tears."
In plain English: Emotionally means doing something based on your feelings rather than logic.
"She spoke emotionally about her childhood memories during the reunion dinner."
Usage: Avoid using this adverb when you simply mean "strongly," as the word specifically requires that feelings be visibly displayed rather than just felt intensely. It often sounds more natural in formal writing than casual speech, where phrases like "really" or "deeply" might suffice.
The word emotionally comes from combining the adjective emotional with the suffix -ly to form an adverb. It entered English by attaching a common grammatical ending to describe actions done in an emotional manner.
