adjective
real, genuine
A2
echt: adjective meaning 'real' or 'genuine'. Gradable (comparative: echter, superlative: am echtesten). Antonyms include falsch and künstlich. Not a participle. Used both attributively and predicatively (e.g., das ist echt). Informally also an adverbial 'echt' meaning 'really' or 'very' in colloquial German.
Examples
Das ist echt.
That is real.
Der Händler behauptete, das Gemälde wäre echt, obwohl mehrere Experten Zweifel geäußert hatten.
The dealer claimed that the painting was genuine, although several experts had expressed doubts.

Imagine a real gold coin stamped 'Echt' to show it's genuine
sounds like English 'etch' (something real leaves a mark)
Notes
Used both as adjective ('a real problem') and informally as an adverb ('Das ist echt gut' = 'That's really good').
