"Variant of Abdullah"
The name Abdulloh is commonly a male name from the "Arabic" origin.
Abdulloh is a spelling of Abdullah, the Arabic name built from ʿabd, meaning servant, and Allāh. The -oh ending follows Central Asian transliteration practice, principally Uzbek Latin and Tajik, where the final long vowel is written o rather than the -ah of the common English spelling. The elements and meaning are the same as in Abdullah; only the rendering in Latin letters differs.
Abdullah means "Servant of Allah.".
The pronunciation of Abdulloh is ab-DOOL-oh.
