See also: Appendix:Variations of "mal"
- The unchanged plural (without -e) is obligatory after numerals. These combinations are always written as one word: einmal (“once”), zweimal (“twice”), dreimal (“three times”), hundertmal (“a hundred times”), and so on.
- The unchanged plural may or may not be used after alle (“all”) and beide (“both”). These combinations are written as separate words according to the new spelling. Thus: alle Mal or alle Male (“all times, each time”); beide Mal or beide Male (“both times”). Older spelling, however, had beidemal and allemal for the endingless variants.
- Nota bene: The word allemal does still exist in contemporary spelling, but is distinct from alle Mal as above. It is an adverb meaning “at any rate”, and sometimes “always”.
