An alphabetical word (also called an Aeolian word) is a word whose letters appear in strict ascending alphabetical order from first to last.
In recreational linguistics, finding words whose letters follow the natural order of the alphabet (A through Z) without ever going backwards is a classic challenge. Common 6-letter English words in alphabetical order include "almost", "biopsy", "chintz", and "effort". The longest non-technical word recognized in major dictionaries is the 8-letter botanical term "aegilops" (a genus of grasses) and 7-letter words like "beefily" and "billowy".
