Count: 0 — No standard English pronouns begin with the letter L. For students, teachers, editors, ESL learners, writers, and linguistics enthusiasts building an A–Z reference of English pronouns, the L entry is empty: major dictionaries and grammar handbooks list personal, possessive, reflexive, relative, demonstrative, interrogative, indefinite, reciprocal, and distributive pronouns, but none start with L. Interesting detail: several common L-words (little, less) sometimes stand alone in sentences, yet grammars treat them as determiners or quantifiers rather than as members of the pronoun class.
Explain why the search returns nothing. Pronouns form a small, closed class that has evolved from Old English and related Germanic roots; the historical and morphological patterns that produced pronouns in English did not yield any L-initial forms. Consult authoritative sources (for example, the Oxford English Dictionary and standard grammars such as the Cambridge Grammar of the English Language) and you will find complete pronoun lists with no L entries. Distinguish clearly between pronouns and look-alike words: adjectives, determiners, and quantifiers can sometimes function alone, but they are not treated as pronouns in standard reference works.
Note what comes closest and what to do next. Words beginning with L that may seem pronoun-like include little or less when they appear without a noun, but they remain determiners/quantifiers in usage notes. Dialectal or archaic claims of L-initial pronouns are rare and not accepted in major references. Remember that many other languages do have pronouns beginning with L (French le/la/lui, Spanish lo/le), so ESL learners may expect such forms; for an English A–Z list, present the L page as empty but provide cross-references to adjacent letters and to related categories (determiners, quantifiers) where L-words are listed.
