In various dialects, the umlaut became even more important as a morphological marker of the plural after the apocope of final schwa ("-e"); that rounded front vowels have become unrounded in many dialects does not prevent them from serving as markers of the plural given that they remain distinct from their non-umlauted counterparts (just like in English "foot" – "feet", "mouse" – "mice"). The example "Gast" "guest" vs. "Gäst(e)" "guests" served as the model for analogical pairs like "Tag" "day" vs. "Täg(e)" "days" (vs. standard "Tage") and "Arm" "arm" vs. "Ärm(e)" "arms" (vs. standard "Arme"). Even plural forms like "Fisch(e)" "fish" which had never had a front rounded vowel in the first place were interpreted as such (i.e., as if from Middle High German **"füsche") and led to singular forms like "Fusch" that are attested in some dialects.
