“Why do some people say “Shalosh Seudos”? They are not eating three meals at once. “Third Meal” is “Seuda Shelisheet/s/th (for Teimanim). “
Same reason why people say “gonna” and “wanna” instead of “going to” and “want to”….people are lazy!
Can’t explain further…I gotta run ta the store cause I wanna buy food for Shala shudis….
