milk
酥 centers on milk, specifically as a rich, creamy dairy product. The meaning is narrow and concrete, without strong abstract extensions.
酥 combines 酉 (a wine or fermentation vessel) with 禾 (grain). The exact historical development is uncertain, but it likely relates to a fermented or grain-based dairy product.
The left side 酉 suggests a container for liquids, and the right side 禾 looks like a grain plant. Picture a jar of creamy milk made from grains, like a thick rice milk.
For ソ, imagine a soft, creamy milk: the word 'soft' starts with ソ, and the milk is smooth and rich.
