Irregularly spelt common words

Shown below are 4,219 common words with unpredictable spellings. Only 2,828 have irregular spellings like ‘fruit’, but they make another 1,389 unpredictable. –  Long /oo/, for example, is spelt mainly oo (in 94 words like ‘food, soon’). But because they are outnumbered by 103 words in which long/oo/ is spelt differently (e.g. rude, shrewd, move), the spellings for long /oo/ all have to be learned one by one, in all 197 words.

      Next to the words with irregular spellings are shown respellings which conform to the main English spelling patterns. – Theyhelp to clarify their irregularities, and for words which pose both reading and as spelling difficulties, they also provide guides to pronunciation. 

    The tricky words are listed in the following order:

1) Words with irregular spellingsfor clear vowels and consonantsin alphabetical order of

     the spellings which they disobey,  i.e.  A,  a-e-ain air-ar,  au-aw,  -ay,  … .

2) Irregular spellings for unstressed vowels (e.g. flatten, certain, mutton)

3) Unpredictably doubled consonants (rabbit habit, very merry, shoddy body).

    The figures [in brackets] show how many of the 7,000 most used words which I analysed use the pattern  and how many do not.  Redundant or surplus letters are shown in red (e.g. have, debt, touch).

Heterographs, such as ‘ale/ail‘, are reduced to a single spelling [ale], like the 2,500 other English words which have just one spelling for their different meanings (e.g. bar, post, round).

It creates reading problems in 7 longer words:
     Ally, apply, deny, supply, magnify, multiply, rely,  verify – (Cf. tally, subtly, puffy…).

They would be better as: allye, aplye, denye, relye, suplye, magnifye, multiplye, verrifye.

Z – (zap, rise) –[16- 1] for an initial /z/ sound: 

Zany, zap, zeal, zebra, zenith, zero, zest, zigzag, zinc, zip, zither, zodiac, zone, zoo, zoom, Zulu.


 In the middle of words the main spelling for the z-sound is (desire, result) and in 
endings –se (rise). –  See –s- and –se.

2) Unstressed vowel problems

Only stressed English vowels can be heard clearly, and most English words have just one of them

(butter, describe, understand). The unstressed vowels range from fairly audible (bicycle) to almost nonexistent.

      They occur mainly in endings and prefixes, and their spellings are very irregular:

laughable – compatible,   primary – mistery – factory,   madden – abandon – urban – villain, 

confidence – guidance,   competent – distant,   fitter – actor; 

deserve – disaster; indulge – endager.

      Because their spellings take much learning, and because it helps to exaggerate their pronunciation while doing so, many people end up thinking that they can detect differences in their pronunciation and would find their altered appearance shocking. In ordinary speech, all unstressed vowels sound much the same.

      They cause no reading difficulties. Standardising them would therefore not make learning to read English any easier, only to spell. They are therefore perhaps in less urgent need of reform, despite creating much pointless memorisation of spellings. 

 –able/ –ible – [33 – 17] –  (doable – feasible)

-le – (dangle, apple – channelmorsel) – [175 – 27] –  -le is the main spelling for a final l-sound  after several consonants,  except:

ary / -ery / -ory / -ry –  (37 –ary / 58 others)- utterly unpredictable.

            ‘Carpentry, chemistry, etc.’ suggest that the vowels before –ry are nearly all redundant.

-er   /-or /-our… – (after, actor, nectar, armour;  butcher, culture) – [315 – 170]
     In US English 7 words which have –re endings in the UK have already been modernised.

Additionally, 18 British –our endings have been shortened to –or (labour – labor) in US, but these still need to be learned as exceptions from the –er pattern, just like the other 75 words which end in –or.

are made longer with suffixes like  –ed,  -er,  –ing   or  –y, their last consonant gets doubled

to show that their vowel is short rather than long:  

        batted,  batting,  bitty   –  bated,  bating, biting.

At least 503  root words of more than one syllable (listed at the end of this section) also have doubled consonants (or  ck, dg)  to show that their main vowel is short rather than long:

        e.g.  fatten,  teddy,   dinner,  popper,  supper,   pocket,  fridge  –

            cf. fatal,    tedious,  diner,     pope,      super,      poker,  oblige.

But in the 7,000 most used English words which I examined

              575 words are without doubling (habit, study – c.f. rabbit, muddy) and

              219  wordshave needlessly doubled consonants (e.g. arrive – cf. arise).

This makes English consonant doubling almost completely unsystematic

Of the 575 words of more than one syllable which do not indicate their short, stressed vowels:

            328 have no other irregularities apart from their undoubled consonants

                     (e.g. body, copy, study –  cf. shoddy, poppy, muddy),

              73 do not use ckdgss and zz

                     (e.g.  placard,  agile,  acid,  scissors  –  c.f.   packet,  badger, massive, blizzard)                       and  174  words have assorted other irregularities as well

                     (e.g. women,   foreign  –  cf. swimmer;   sorry, flatten).
