hackmatack

The story

1. Proto-Algonquian · derived from*-a·xkw-“hardwood or deciduous tree”
2. English todayhackmatack

Believed to derive from Abenaki, though no specific etymon has been found. The term is first attested in the 1760s–90s, when it was spelled hakmantak and referred to dense forest. In European languages there was contamination between tacamahac, from Nahuatl, and various Algonquian words containing the final Proto-Algonquian *-a·xkw- (“hardwood or deciduous tree”), including the sources of tamarack and hackmatack, as was already recognized by Chamberlain 1902. This makes the precise Algonquian words involved difficult to recover. Compare the late 19th century German Low German term Hackemtackem (“tacamahac (medicinal resin)”).
