Editing: finding one mistake in each line

An editing passage has exactly one error per marked line, and it is always spelling or grammar. Knowing there is exactly one — and exactly what kind — is most of the technique.

01 One line, one error

The instruction is precise: each marked line contains one error. Not two, not none.

So if you find one, stop looking at that line. And if you find none, look again — it is there, and it is usually the word you read past.

Write the whole corrected word, not just the letter you changed. A correction that is itself misspelt scores nothing.

1 The childrens were exited about the trip.children · excited2 They packed their bags and wait at the gate.waited3 Everyone was hopping the bus would come soon.hoping
Line 1 shows the trap: two errors look present, but only one is the marked kind.

02 The errors that actually appear

The same handful come round every year, which makes them worth checking for deliberately.

A table of common editing errors: spelling, subject-verb agreement, tense, plurals, prepositions and articles
Kind of errorWhat to check
Spellingdouble letters, ie/ei, silent letters, -ing rules
Subject–verb agreementhe go → he goes; they was → they were
Tenseone tense throughout, unless the passage changes time
Pluralschildrens, sheeps, informations
Prepositionslisten to, good at, depend on, arrive at
Articlesa before a consonant sound, an before a vowel sound
Subject–verb agreement and tense are the two most common grammar errors.

03 A method that finds them

Reading for meaning skips over errors, because your brain repairs them silently. Read differently.

  1. Read one line at a time, not the passage as a story.
  2. Say it in your head. Agreement and tense errors are heard more easily than seen.
  3. Check every verb against its subject and against the tense the passage is in.
  4. Check every plural, then every preposition, then every article.
  5. If you still see nothing, suspect a spelling you read past because you knew the word.

04 The spelling rules worth knowing

A small set covers most of what appears.

Adding -ing: a short vowel before a single final consonant doubles it — hop → hopping. A silent e is dropped — hope → hoping. That pair is the single most common editing error there is.

Adding -ed: the same doubling rule — stop → stopped, hope → hoped.

Plurals: words ending in a consonant + y change to -ies (baby → babies); words in -f or -fe often take -ves (leaf → leaves).

i before e except after c, when the sound is eebelieve, but receive.

Irregular plurals do not take -s at all: children, men, women, feet, teeth, sheep, mice.

05 How to say them

These are words most children have never said out loud, and a word you cannot say is a word you avoid using. Capitals mark the syllable you lean on. Tap the speaker to hear it.

07 Mistakes worth knowing about

Each of these is wrong. Decide why before you open it.

  • “I found two errors in one line, so I corrected both.”

    There is exactly one of the marked kind. Correcting an extra can cost you the mark.

  • “I could not find an error, so I left the line blank.”

    There is always one. If nothing is visible, check verbs, plurals and prepositions in turn.

  • “hoping and hopping are the same word.”

    Hope loses its e — hoping. Hop doubles its p — hopping. Different words, and the commonest error in the topic.

  • “I wrote just the letter that changed.”

    Write the whole corrected word, spelt correctly.

  • “I read the passage through and it sounded fine.”

    Reading for meaning hides errors. Read line by line and check verbs against subjects.
