The Letter C Sounds Different in "City" and "Cat" — Here's the Rule Behind It

The c in city is /s/. The c in cat is /k/. Same letter, two different sounds, and the usual instinct is to file it under "just memorize every word."

You don't have to. In English spelling, which sound c makes is decided almost entirely by the single letter that comes right after it.

The rule for C: check the next letter

If c is followed by e, i, or y, it's soft: /s/. If it's followed by anything else — a, o, u, a consonant, or the end of the word — it's hard: /k/.

• Soft /s/: city /ˈsɪti/, cent /sent/, cell /sel/, circle /ˈsɜːkl/, bicycle /ˈbaɪsɪkl/
• Hard /k/: cat /kæt/, cup /kʌp/, cold /kəʊld/, class /klɑːs/, music /ˈmjuːzɪk/

This rule has almost no exceptions. It's so reliable that most people never notice it's a rule at all — they just assume each word happens to sound the way it does.

G follows the same logic, but less faithfully

If g is followed by e, i, or y, it's usually soft: /dʒ/. Followed by anything else, it's hard: /ɡ/.

• Soft /dʒ/: gem /dʒem/, giant /ˈdʒaɪənt/, gym /dʒɪm/, age /eɪdʒ/, giraffe /dʒɪˈrɑːf/
• Hard /ɡ/: go /ɡəʊ/, gap /ɡæp/, gold /ɡəʊld/, garden /ˈɡɑːdn/

But G has a stubborn set of exceptions

get /ɡet/, give /ɡɪv/, girl /ɡɜːl/, gift /ɡɪft/, tiger /ˈtaɪɡə/ — every one of these is followed by e or i, and every one is hard. That's not random: the soft-G pattern arrived with the flood of French and Latin loanwords after the Norman Conquest. Get, give, girl, and gift are older, native English words (mostly from Old English or Old Norse) that predate that pattern and never picked it up.

There's also a whole category of words that spell their way around the rule on purpose: guess /ɡes/, guitar /ɡɪˈtɑː/, guide /ɡaɪd/. The u here is silent — its only job is to sit between g and e/i and force the hard sound. Queen-type words do something similar with c, but that's a fixed qu combination and outside this rule entirely.

How to use it: glance right before you speak

Hit an unfamiliar word, and checking the letter right after c or g is faster and more accurate than guessing. C almost never breaks its own rule. For g, just keep get/give/girl/gift on hand as your exception list, and let the rule handle the rest.
