What is a head word in dictionary?

In a dictionary, the headword is the main word being defined. It's the word that appears in bold or a larger font at the beginning of each entry.

Here's a breakdown:

* It's the word you're looking up. For example, if you're looking for the definition of "cat," "cat" would be the headword.

* It's usually the most important word in the entry. The definition and other information in the entry relate to the headword.

* It's often followed by pronunciation information. This can be phonetic symbols or a pronunciation guide.

* It can be a noun, verb, adjective, adverb, etc. Dictionaries are organized alphabetically by headword.

Essentially, the headword is the "star" of the dictionary entry, and everything else revolves around it.
