סתם "לחם" בדיוק הוא של חטים, ו"קלוי" הוא גם משעורים. וכשאמר "לחם וקלוי" נדע שגם שם 'לחם' בא בהרחבה וכולל אף של שעורים (אמור סימן ס)
Ayelet Hashachar, translated by Betzalel Avraham Feinstein, 2021
Ordinary לחם (bread) in its precise meaning is made of wheat, while קלוי (toast) can also be from barley. And when it says לחם וקלוי, it is known that also the noun לחם comes in its broad meaning and even includes bread made of barley.
