erect

erect: [14] Erect was borrowed from Latin ērectus, the past participle of ērigere ‘raise up, set up’. This was a compound verb formed from the prefix ex- ‘out, up’ and regere ‘keep straight, set, direct’ (source of English regent, region, etc). The use of the derivative erection [15] for the enlargement of the penis dates from the 16th century.
=> correct, direct, regent, region
