Also im not sure thisnis even accurate of the script. The latin script evolved from a common rood language (indo european). While it is true the germanic language branched off before the evolution into latin script, and lost the indo european script and was largely oral, it readopted latin which was related to its earlier common script. Id imagine this or similar is true for some of the other language families. However cyrilic never adoped latin and is also from thr indo-european root, it evolved seperately from the common root script.
