Wirklich is an adverb and sometimes adjective meaning 'really' (intensifier) or 'real' (actual). Use: Das ist wirklich gut (really good). It is gradable: comparative wirklicher, superlative am wirklichsten. Antonym unwirklich. Not a participle; when adjectival it inflects for gender, number and case.

Imagine a stamp that says 'REAL' over a document — that confirms it's wirklich (real/really).
Sounds like 'wirk-lich' — 'wirk' like 'work' + 'lich' like 'lick' — think of something that truly 'works' as real.
Notes
Wirklich is commonly used as an adverb ('really') and as an adjective ('real'). Context determines the meaning.
