The word "underlaying" is derived from two main components: "under" and "lay".
"Under" comes from the Old English "under", which means "beneath" or "below". It has Indo-European roots and can be traced back to the Proto-Germanic word "under". This word evolved into various forms across different Germanic languages, including Old Saxon "undar", Old Frisian "under", Old Norse "undir", and Middle Dutch "onder".
"Lay" is derived from the Old English verb "lecgan" (present tense "licgan"), which means "to place" or "to lie down". It has origins in the Proto-Germanic word "lagjaną" and shares similarities with other Germanic languages such as Old Saxon "leggan", Old Frisian "lia", and Old Norse "leggja".
