Can "eloheinu" (written in Hebrew letters) be erased, or is it considered mechikath hashem? I could only find prohibition of erasing "elohim", so I was wondering if this could be similar to writing "God" in English.
Just looking for definitive sources on the matter.
Still prohibited. The general rule is (Yesodei HaTorah 6:3, YD 276:9) prefixes conjugated to one of God's names are permitted to erase while suffixes are prohibited (without statutory punishment). The root name though is definitely fully prohibited.
So derivatives of א-לוה or א-להים like א-להיך א-להינו א-להי א-להיכם are all prohibited (though you couldn't be punished for erasing the last letters).
