'Esszimmer' (dining room) is a compound noun made from the verb 'essen' (to eat) and the noun 'Zimmer' (room). The 's' in the middle is a linking element that connects the two parts. Literally, it is a 'Zimmer zum Essen' (room for eating).

Pay attention to the prepositions and the case. When you are located in the room, you say 'im Esszimmer' (in the dining room, dative). When you go into the room, it is 'ins Esszimmer' (into the dining room, accusative).

'Speisesaal' and 'Esszimmer' are both rooms where people eat. The difference is mainly the location and size. A 'Speisesaal' is usually a large room in a hotel, school, hospital, or similar institution where many people eat. An 'Esszimmer' belongs to an apartment or house and is used privately. The words can be confused because both have to do with meals. For public or larger institutions, 'Speisesaal' fits; at home, 'Esszimmer' sounds natural.
