Count: 0 — No authentic Egyptian boy names begin with the letter X. This absence reflects how both modern Egyptian Arabic and the reconstructed sounds of ancient Egyptian are written and transliterated in Latin script. An interesting detail is that names familiar to English speakers that start with X (for example, Xerxes) are foreign imports used in Egyptian history or literature, not native Egyptian names, so they do not meet the criteria for an authentic Egyptian male name starting with X.
Understand that the Arabic alphabet used in modern Egypt has no native letter that corresponds to the Latin X. Transliteration systems render Egyptian Arabic and ancient Egyptian consonants with symbols such as kh (خ), sh (ش), ḥ, and ḫ rather than X. Scholarly name corpora and modern Egyptian name lists therefore do not produce entries that begin with the Latin X, and standard references in Arabic onomastics and ancient-Egyptian studies confirm this pattern.
Check instead for close and valid alternatives. Look for names beginning with Kh, K, Sh, S, or H in modern Egyptian name lists, or for well-documented ancient Egyptian names recorded in transliteration (using characters like ḫ and š). Prioritize vetted sources — modern Egyptian name lists, Arabic onomastic guides, and scholarly ancient-Egyptian corpora — and verify spellings, pronunciations, and meanings before using a name.
