when to double a consonant before adding -ed or -ing to a verb – Speakspeak

We add -ing to a verb to form its present participle, and -ed to regular verbs to form the past simple. When doing this, we sometimes double the last letter of the verb, as in these examples:

• stop ⇒ stopped, stopping

  stoped

  stoping

• refer ⇒ referred, referring

  refered

  refering

Sometimes, however, we don’t double the last letter, as with the verb visit:

• visit ⇒ visited, visiting

  visitted

  visitting

To understand this spelling rule, it’s first necessary to know the meaning of vowel and consonant:

vowels = a  e  i  o  u
consonants are all other letters (b  c  d  f  g, etc).

The rule

We double the final letter when a one-syllable verb ends in consonant + vowel + consonant.*	stop, rob, sit	stopping, stopped, robbing, robbed, sitting
We double the final letter when a word has more than one syllable, and when the final syllable is stressed in speech.	beGIN, preFER	beginning, preferring, preferred
If the final syllable is not stressed, we do not double the final letter.	LISten, HAPpen	listening, listened, happening, happened

In British English, travel and cancel are exceptions to this rule:

travel, travelling, travelled; cancel, cancelling, cancelled.

* We do not double the final letter when a word ends in two consonants (-rt, -rn, etc.):
start – starting, started; burn - burn, burned.

* We do not double the final letter when two vowels come directly before it:
remain – remaining, remained.

* We do not double w or y at the end of words:
play – playing, played; snow - snowing, snowed.

Double consonants. Double consonant words - Russian

§6

In Russian, words with double consonants in the root are found quite often in foreign words, as well as in some Russian words. Most often in Russian words, a doubled consonant occurs at the junction of a root and a suffix, as well as at the junction of a prefix and a root.

Double consonants in roots

Only double consonants are used in the roots of Russian words ss and lj . There are few such words.

The letters ss are written in the word quarrel and related words formed from it, for example: to ss to shout, to ss to shout ; and also in the words Ro ss iya (from the obsolete ross ), ro ss iya, Beloru ss iya (but Rus, Belarusian ).

Letters LJ are written in words in LiveJournal and, Dro LiveJournal and, Zhu LiveJournal AT, MO LiveJournal Ewella and related related words, for example: Zhi LiveJournal ANINIA, MO LJ Evalle . Letters LiveJournal are also written in words and forms formed from the verb to burn ( tourniquet ), for example: LiveJournal 111111111111111111111111111, LJ 1111111111111111111 fj em .

Double consonants at the junction of a prefix and a root

Double consonants in Russian words are written at the junction of a prefix and a root if the prefix ends and the root begins with the same consonant, for example: , in sz rhenium, according to dd hold, o tt excut .

Notes:

1. With the letters ss words formed from the root -count- 9 are written0012 using the prefix ras - for example: ra ss read, ra ss read . Words with the same prefix and root -th- are written with one with , for example: calculation, calculating (but countless , from without counting ).

2. Double consonants can occur in suffixes and at the junction of a root and a suffix, for example: traditional nn th, unity nn th, matro ss cue . These cases will be considered later.
