Query Regarding memory alignment /access

Hi All, I have 2 questions regarding memory access/alignment 1: can aligned/unaligned virtual address could translate to unaligned/aligned physical address ? or aligned virtual --- > aligned phy and unaligned virtual --- > unaligned phy ?? 2: Since the cpu access the memory in word size, for a large buffer, (say size N bytes where N > wordsize) isn't it sufficient for buffer to be properly aligned if its address % WORD_SIZE == 0? rather than address % N == 0 check?? since cpu, anyways will not access more than word size at a time so any address which is divisible by wordsize is by default properly aligned? Please share your inputs.
