Pro Tip
Context is key
Always check whether 'als' is used for time, comparison, or role. For example, 'Er ist größer als ich' (comparison) vs. 'Ich war müde, als ich ankam' (time).
Gold Rule
Temporal 'als'
Use 'als' for a single past event or a specific point in time. For repeated past events, use 'wenn'.
Comparative 'als'
Always use 'als' after comparative adjectives or adverbs (e.g., 'besser als', 'schneller als').
Word Origin
From Old High German 'alsō', related to Old English 'ealswā' (as, like) and Gothic 'als' (as).
Usage Notes
The meaning of 'als' depends heavily on context—temporal, comparative, or role-based. It is not interchangeable with 'wenn' (if) or 'wann' (when) in all cases.
