Look at Linear A and Linear B side by side and something jumps out: many signs have nearly the same shapes. That is no accident; Linear B was adapted from Linear A (A Family of Aegean Scripts). It also gives us a way to sound out Linear A, with a warning label attached. (Recall the special signs of Special Signs; some of them are shared too.)
Key idea
| Linear A | AB number | Linear B | Read |
|---|---|---|---|
| 𐘀 | AB01 | 𐀅 | da (by convention) |
| 𐘂 | AB03 | 𐀞 | pa (by convention) |
| 𐙂 | AB81 | 𐀓 | ku (by convention) |
| 𐘁 | AB02 | 𐀫 | ro (by convention) |
| 𐘸 | AB67 | 𐀑 | ki (by convention) |
| 𐘞 | AB31 | 𐀭 | sa (by convention) |
| 𐘴 | AB60 | 𐀨 | ra (by convention) |
| 𐙁 | AB80 | 𐀔 | ma (by convention) |
Why borrow the values at all?
Because there is some evidence that many carried over. Place names give the best: the Linear A word read pa-i-to with the borrowed values is the same as Linear B pa-i-to, Phaistos, and Hagia Triada, where it appears, is next to Phaistos. Other words, such as su-ki-ri-ta and se-to-i-ja, appear in both scripts as names of Cretan places. If the values were wrong, such matches would be unlikely.
Why it works
Common mistake
Worked example: Read by convention
- Both signs match Linear B ku and ro.
- By convention, Linear A takes the Linear B values.
Answer: Read by convention as ku-ro; the sounds are a working guess.
Worked example: What supports the convention?
- Read with the borrowed values, Linear A words like pa-i-to match Cretan place names also found in Linear B.
Answer: Place names like pa-i-to come out the same in both scripts.
