Customer Service and Business English: A Student's Guide

Introduction

Relative pronouns connect ideas by linking a noun (person, place, thing, or time) to extra information about it. They help make sentences more precise and avoid repetition — especially useful when you study alone and want clear, compact notes.

Definition: Relative pronouns are words that introduce relative clauses, giving more information about a noun mentioned earlier.

What relative pronouns do

  • Link a main clause to a relative clause
  • Refer back to a person, place, thing, time, or reason
  • Can act as subject, object, or show possession in the relative clause

Main relative pronouns and uses

PronounUseExample
whoPeople (subject)The teacher who teaches English is very nice.
whomPeople (object)The man whom I met yesterday is a lawyer.
whosePossession (people/things)The boy whose phone is missing is looking for it.
whichThings or animalsThis is the cake which she baked yesterday.
thatPeople or things (restrictive)I like the movie that we watched last night.
wherePlacesThis is the city where I was born.
whenTimeDo you remember the day when we met?
whyReasonThe reason why I left early was my headache.
whatThings / nominal relative (thing + idea)I didn't understand what she said.

Notes on usage

  • Use who when the relative pronoun is the subject of the clause: "The student who studies hard will pass."
  • Use whom when it is the object: "The student whom the teacher praised smiled." You can often replace whom with "him/her" to test correctness: "I met him yesterday" -> "whom I met yesterday."
  • That vs which: Use that for essential (restrictive) clauses without commas, and which for nonessential (nonrestrictive) clauses often set off by commas: "The car that has a dent is mine." vs "My car, which has a dent, is for sale."
  • Whose works for possession with people or things: "The company whose logo changed announced a rebrand."
  • Where, when, why introduce clauses about place, time, and reason.

Definition: A restrictive clause gives necessary information to identify the noun; a nonrestrictive clause adds extra information and is set off by commas.

Building sentences with relative pronouns (step-by-step)

  1. Identify the noun you want to describe (person, place, thing, time, reason).
  2. Decide whether the extra information is essential (restrictive) or extra (nonrestrictive).
  3. Choose the correct relative pronoun based on role (subject/object/possession) and meaning (place/time/reason).
  4. Attach the relative clause right after the noun it describes.

Examples and transformations:

  • Combine two sentences: "I met a woman. She is a writer." -> "I met a woman who is a writer."
  • Make object relative: "I met the author. I admired her book." -> "I met the author whom I admired." or more naturally "I met the author whose book I admired."
  • Use where: "This is the café. We had our first date there." -> "This is the café where we had our first date."
  • Use when: "I remember the night. We danced all night." -> "I remember the night when we danced all night."

Practical tips for not-attending learners

  • Practice by joining two short sentences into one using a relative pronoun.
  • Listen to podcasts or read short news articles and underline relative clauses.
  • Write 5 sentences daily describing people, places, and things around you using different relative pronouns.
💡 Věděli jste?Fun fact: English once used "whom" far more often; today many native speakers use "who" in both subject and object positions in informal speech.

Common mistakes and how to avoid them

  • Wrong: "The woman who I met yesterday is a lawyer." (acceptable informally) Better/standard: "The woman whom I met yesterday is a lawyer."
  • Wrong punctuation with nonrestrictive clauses: "My brother who lives in New York is visiting." Correct non
