How it works
Spelled by ear, could comes out cud or cood: five letters, three sounds, a silent l. This could sight word sheet has the child trace it, circle it among cold, cloud and would, and build it from five tiles.

Where the silent l came from
Wiktionary traces could to an Old English past form of can with no l. The l was written in during the early 1500s so that could would match should and would. It is silent in all three. That leaves o-u-l sharing one vowel, the short oo of good, with only the c and the d to hear. Teach o-u-l-d as one chunk.
The same five letters as cloud
Could and cloud use the same five letters, and only the l moves. Cold is could without its u. A child who remembers that an l goes in somewhere can land on either one. One sentence near the foot of this page, under The sight words and their practice lines, holds both: I could see a cloud.
- Chant the letter names, c-o-u-l-d, in a steady beat while tracing. Sounding out gives only the c and the d.
- Once could is solid, write would could should. The child underlines the four letters all three words share.
- Wikipedia's table of the Oxford English Corpus ranks could 67th among English words.
Questions and answers
Is the sight word could one to sound out?
Only at its two ends, where c and d make their usual sounds. The middle has to be known by heart. Could rhymes with good, wood and hood, and none of them spells the vowel its way.
How do I explain what could means?
Show its four jobs with four sentences. It is the past of can: I could swim at six. It asks politely: Could I have a turn? It says maybe: It could rain today. It offers an idea: You could go first.
My student writes cloud or cold for could. Which rows help?
Write could cloud could and could cold could on the board. Then write the missing-letter row c_uld co_ld cou_d, which drills the middle letters in order. None is on the printed sheet. Have the child say the letter names aloud for every gap.
