Rune for a in old English ae?

There isn't a single rune that directly represents the "ae" digraph in Old English. Here's why and how we can address this:

* Old English Runes: The runic alphabet used in Old English (Anglo-Saxon Futhorc) didn't have a specific rune for the sound "ae." It was typically represented by the rune Æ, which was a combination of "A" and "E."

* Sound Representation: In Old English, the sound represented by "ae" was a long vowel, similar to the modern English "ay" in "say." It was often spelled as "ā" using the rune Ā.

Here's how you can represent "ae" using runes:

* Use Æ: This is the most traditional and accurate representation, though it's not strictly a single rune.

* Use Ā: This reflects the pronunciation more closely, as "ae" was often pronounced as a long "a" sound.

* Use "A" and "E": In some cases, you can use the individual runes "A" and "E" to represent "ae," especially when you're focusing on the individual sound components.

Ultimately, the best way to represent "ae" in runes depends on your specific context and desired level of accuracy.
