Synonym discussion
Sense: adjective/1
All four words describe something positive you want to engage with, but each captures a different feeling. 'Memorable' is the broadest — a memorable speech, meal, or trip stays in your mind because it was special in some way. 'Catchy' is narrower: it focuses on sound-related things (tunes, slogans, names) that are easy to remember and tend to repeat in your head without effort. 'Infectious' adds the idea that the feeling spreads: an infectious laugh makes other people laugh too, and an infectious tune makes others hum along. 'Addictive' is the strongest — it suggests you cannot stop, as in 'an addictive TV series' or 'an addictive mobile game'. 'Appealing' is the most general; it simply means attractive or pleasant, with no implication that you will remember it later. For a song you keep singing under your breath, 'catchy' is the exact word; for a film you still think about years later, use 'memorable'; for a show you binge-watch all weekend, use 'addictive'.

Etymology
Formed in English by combining the verb 'catch' (from Latin 'captiare', meaning 'to chase or seize') with the suffix '-y', which turns verbs into adjectives meaning 'having the quality of'. The earliest recorded use of 'catchy' in the 1700s meant 'fitful' or 'irregular', like a catchy (intermittent) breeze. By the 1830s the modern sense of 'pleasing and easy to remember' emerged, first applied to tunes — a melody that 'catches' the listener's attention. The 'tricky' sense appeared in the late 1800s, describing something that catches you off guard.
