Synonym discussion
Sense: adjective/1
All four describe a positive reaction, but they differ in intensity and source. 'Amused' is the quietest — it suggests a small smile rather than a loud laugh, and the trigger is usually something funny or odd. 'Entertained' is broader: you can be entertained by a long film, a magic show, or even a busy afternoon, with no humour required. 'Tickled' is informal and personal, suggesting a private delight at something cute or unexpected, as in 'I was tickled when she remembered my birthday.' 'Delighted' is the strongest and warmest — it shows clear pleasure, often at good news or kindness, as in 'Grandma was delighted by the homemade card.'

Etymology
'Amused' is the past participle of the verb 'amuse', which entered English from Middle French 'amuser' meaning to make someone stare or distract. The original sense was about diverting someone's attention rather than making them laugh. The modern meaning of finding something funny developed gradually in English from the late 1600s, as the word shifted from 'distract' toward 'pleasantly entertain'.
