What 샊 means
It is one Korean syllable, not a word with its own definition. A Hangul block combines a starting consonant, a vowel, and sometimes a closing consonant; in 샊, those parts are ㅅ, ㅐ, and ㄲ.
Hangul's letters were created in 1443; the 1446 guide Hunminjeongeum explains their sounds and how they combine into syllables. The script gave Korean speech a systematic written form. Its square blocks arrange sound letters together, but Hangul letter shapes are not directly derived from Chinese characters.
The script's names also vary by time and region. The name Hangeul appears in the 1910s and was widely used by 1928; South Korea commonly uses Hangeul, North Korea prefers Choseongul, and Jeongum is a neutral name.
What does 샊 mean alone?
It gives too little context to identify a word. Ask which word or sentence it belongs to; the Korean text around it carries the intended meaning.
Neutral as part of Korean text; alone, 샊 reads as an unexplained syllable fragment.
Don't infer a full word from this syllable alone.
