Remember that 'impatience' is a noun. If you want to describe HOW someone acts, use the adverb 'impatiently' (e.g., 'He waited impatiently').
Impatience is often followed by the preposition 'with' when specifying the cause (e.g., 'impatience with the delay').
From Old French 'impatience', from Latin 'impatiens' (unable to bear), from 'in-' (not) + 'pati' (to suffer/endure).
Use 'impatience' when describing a person's emotional state regarding delays. It is a noun, so it cannot modify verbs directly (use 'impatiently' for that).
