凡

Outer frame 几 - the indexing radical, here the two-stroke outline that hooks down on the right. 凡 etymologically came from a pictograph of a casting mould or floor plan (totally unrelated to a table); modern stroke-count convention files it under 几 because the silhouette matches. Provides the bordering frame around the inner dot.

Inner marker dot - distinguishes 凡 from the otherwise-identical 几 (table). In the original casting-mould reading, the dot represents the contents poured into the form, giving the meaning 'every instance that fits the standard'. Without this single dot the character is just 几; with it, it means 'all, every, ordinary' (凡是, 凡人, 不平凡).
