ESL Editing in Los Angeles

Los Angeles is one of the most multilingual cities in the United States. Large communities of Spanish, Mandarin, Cantonese, Korean, Armenian, Tagalog, and Persian speakers live and work across the county, and many produce important academic and professional writing in English as a second language. ESL writers at every level benefit from editing that understands the structural differences between their first language and English.

Common patterns that arise for Spanish writers include subjunctive constructions and gendered article agreement that don't map cleanly to English. Mandarin and Cantonese writers often omit articles and drop subject pronouns. Korean writers frequently produce relative clause placement and tense patterns rooted in Korean grammar. Armenian writers carry over SOV word order and agglutinative constructions. These aren't signs of weak writing ability. They're predictable structural patterns, and experienced editors know how to address them while preserving the author's voice.

• ESL academic editing: Journal articles, theses, and dissertations edited with an understanding of the specific grammar patterns that arise from each language background. Learn more about ESL editing.
• ESL business editing: Proposals, reports, and correspondence edited to meet the expectations of English-speaking business partners and clients.
• University application editing: Personal statements, statements of purpose, and scholarship essays polished for applicants whose first language isn't English.
