那儿
nǎēr · HSK 1
that place
📍👉 那 (that) + 儿 (er-suffix) = that place, over there
那 means 'that' and 儿 is the northern Mandarin retroflex suffix that turns nouns into casual location/diminutive forms. So 那儿 literally reads as 'that-place', the spoken northern counterpart to 那里.
那 — 邑 radical 阝(right) + 冄 phonetic
Originally referred to a place name in ancient China, with the right-side 阝 (city/region radical) indicating a settlement and 冄 providing the sound. Over time it lost its geographic meaning and was borrowed as a demonstrative pronoun meaning 'that' or 'those'.
