A word ends with a consonant, a short vowel, and a consonant. I want to add -er, -ed or -ing as a suffix. Do I double the last consonant? It seems logical to do so, so as not to turn the short vowel into a long one.
Bat becomes batted, not bated. Gel becomes gelling, not geling. Makes sense. But every now and then spell check corrects me on this. I think it wanted to change travelled to traveled.
Yes: the general rule for two-syllable words like “travel” is that there are two rules: the American way is one letter, and the British way is two letters.
Thank Noah Webster for that. In US spelling, many of the words that would normally be doubled are not. e.g. traveled/traveler, canceled, worshiped. They look wrong to me and Firefox flags them as wrong also. That’s because I have the UK spelling selected.
My hard copy AHD says it can be both ways, but lists the single “l” first. I use IE8, but my spellchecker is by a third party and it also vomits when in your quote above you use 2 "ll"s.
Primary school stuff: The vowel at the end is able to reach past one letter and poke the previous vowel changing the noise it makes so you need to put another letter in to block it so it can’t reach past. Of course there are exceptions.
Bater - the “e” can reach back, poke the “a” and make it say Ay!
Batter - aha, it can’t reach.
