More Texas red oak

with 29 comments

Among the last displays of colorful fall foliage in Austin each year is that of the Texas red oak, Quercus buckleyi, as seen here from Great Hills Park on December 15th. (The oaks are young and slender; the large trunks are from other kinds of trees.) Now it’s two weeks later and I’m still finding some red Texas red oak leaves, including a few in our back yard.

Sensorily and psychologically it seems that red is the most fundamental color, and it’s a truism of linguistics that the first color word a language creates is the one for red. The Indo-European language root representing the color red has been reconstructed as *reudh-, which is still recognizable thousands of years later in native English red and ruddy. Red-related words English has acquired directly or indirectly from Latin, which is a cousin of English, include rufous, rubeola, ruby, rubidium, rubicund, rubefacient, rubella, robust, rouge, roux, and russet. (If you’re puzzled about robust, it’s based on Latin rōbur, which designated a type of red oak tree; robust conveys the strength of that tree rather than its color.) From Greek, also a relative of English, comes the erythro– in technical terms like erythrocyte and erythromycin.
