Silent Letter Words
Common silent letter words for second graders, grouped by WR, KN, and MB spelling patterns.
These spelling words are a good fit for students who...
- can spell familiar consonant patterns confidently
- recognize that words such as “write” and “know” begin with a letter that is not heard
- have seen words like “write” or “know” in reading, even before reliably spelling their silent letters

Some familiar words contain a letter that is written but not heard. This focused list helps second graders remember three common silent-letter patterns without mixing in too many exceptions.
The words group silent w in wr-, silent k in kn-, and silent b in final -mb. Examples such as write, know, and thumb teach children to recognize the whole spelling pattern rather than write only the sounds they hear. The linked Skill page gives the deeper explanation.
How to practice this list
Sort the words by wr, kn, and mb. Have your child circle the silent letter, cover the model, and spell the word while naming its pattern before checking.
Common attempts include rite, now, or thum. These show sensible listening. Confirm the sounds the child captured, point to the matching pattern group, and let them insert the quiet letter.
Move on when your child can sort the three patterns, include the silent letter in mixed dictation, and repair an omission after naming wr, kn, or mb.
Common questions
Frequently asked questions
- Why do silent letters matter for spelling?
- Silent letters are part of the correct spelling even though they are not pronounced. Students need to learn patterns such as wr, kn, and mb so they do not spell only the sounds they hear.
- Which silent-letter patterns are in this list?
- This list focuses on wr as in write, kn as in know, and final mb as in thumb. Grouping them helps students see that silent letters often appear in predictable places.
- How is this different from a phonics pattern?
- Phonics often maps letters to sounds directly. Silent-letter words teach the opposite problem: a letter may be visible in spelling even when it is quiet in speech.
- What is a common silent-letter mistake?
- Learners often omit the silent letter, writing rite for write or now for know. Naming the pattern before spelling helps keep the hidden letter in place.
