Blends are created when two or more letters are combined to create a new sound that is not represented by any of the individual letters. For example, the letters "bl" in the word "blend" create the sound /bl/.
Digraphs are created when two letters are combined to represent a single sound that is also represented by one of the individual letters. For example, the letters "th" in the word "think" create the sound /th/, which is also represented by the letter "t."
Here are some examples of blends:
* bl - blend
* br - brown
* cl - clap
* cr - cry
* dr - drip
* fl - flower
* fr - frog
* gl - glow
* gr - grow
* pl - play
* pr - proud
* sc - scoop
* sk - skin
* sl - sleep
* sm - small
* sn - snap
* sp - spot

Here are some examples of digraphs:

Blends and digraphs are both important parts of the English language. They can help to create a variety of sounds and make it possible to spell words accurately.
