Synonym discussion
Sense: noun/1
All four words refer to the highest part of an elevated landform, but they differ in shape, scale, and typical usage. 'Hilltop' is the most everyday word, used for any hill regardless of shape — a rounded grassy hill or a rocky one. 'Summit' is more formal and often suggests a deliberate achievement of reaching the very top; it is the standard term for mountaineering and metaphorical achievements. 'Peak' emphasises a pointed or sharp top and is common for both mountains and graphs. 'Crest' specifically describes the highest ridge or line of a hill or wave. While 'hilltop' implies a small flat area you could stand on, 'peak' implies a single point. You would call a gentle grassy rise a 'hilltop' and use 'peak' or 'summit' for a jagged mountain.
