trepantrapann.²

/trəˈpan/

Forms: Also 1600s–1700s trapan, ( trappan).

Etymology: A word of obscure and low origin, probably originally a term of thieves' or rogues' slang. According to the known evidence, originally applied to a person in sense 1 below (quots. 1653, 1657 at sense 1). Thence arose the verb describing the action of such persons, trepan v.², found in various constructions 1656–62. Hence, finally, a second use of the noun as a name of the action, 1665, sense 2 here. The earlier spelling of the noun was trapan , probably formed in some way < trap n.¹ or trap v.¹ The change to trepan , seen first in the verb, may have been due to association with trepan v.¹ (a much earlier and well known word), of which trepan v.² may have been supposed to be some sort of figurative application. No French trapan or trapaner in this sense is recognized by Littré, Hatzfeld & Darmesteter, Cotgrave, Godefroy. Nor is there any reason to connect trapan with Old Provençal trapon ‘sorte de piège’, nor with Italian trapanare = trepan v.¹

Obsolete or archaic.

1. A person who entraps or decoys others into actions or positions which may be to his advantage and to their ruin or loss. Also applied to an animal (quot. 1686).

Etymology: A word of obscure and low origin, probably originally a term of thieves' or rogues' slang. According to the known evidence, originally applied to a person in sense 1 below (quots. 1653, 1657 at sense 1). Thence arose the verb describing the action of such persons, trepan v.², found in various constructions 1656–62. Hence, finally, a second use of the noun as a name of the action, 1665, sense 2 here. The earlier spelling of the noun was trapan , probably formed in some way < trap n.¹ or trap v.¹ The change to trepan , seen first in the verb, may have been due to association with trepan v.¹ (a much earlier and well known word), of which trepan v.² may have been supposed to be some sort of figurative application. No French trapan or trapaner in this sense is recognized by Littré, Hatzfeld & Darmesteter, Cotgrave, Godefroy. Nor is there any reason to connect trapan with Old Provençal trapon ‘sorte de piège’, nor with Italian trapanare = trepan v.¹ Obsolete or archaic. 1. A person who entraps or decoys others into actions or positions which may be to his advantage and to their ruin or loss. Also applied to an animal (quot. 1686).
