What does 'diffident' describe in terms of personality?

The term 'diffident' is used to describe someone who is shy or lacking in self-confidence. Individuals with a diffident personality often exhibit hesitance when it comes to expressing their thoughts or feelings, and they may avoid situations where they have to assert themselves. This aligns with the understanding that a diffident person typically feels uncertain in social interactions, which can lead to a sense of timidity and reluctance to take the forefront in conversations or activities.

In contrast, assertive individuals actively express their thoughts and needs, outgoing individuals are usually sociable and eager to engage with others, and confident persons demonstrate self-assuredness and a strong sense of belief in their abilities. These descriptions do not reflect the qualities associated with being diffident, reinforcing why 'shy' is the fitting description in this context.
