Old High German

Old High German (OHG, German: Althochdeutsch, German abbr. Ahd.) is the earliest stage of the German language, conventionally covering the period from around 700 to 1050 AD. Coherent written texts do not appear until the second half of the 8th century, and some treat the period before 750 as "prehistoric" and date the start of Old High German proper to 750 for this reason. There are, however, a number of Elder Futhark inscriptions dating to the 6th century (notably the Pforzen buckle), as well as single words and many names found in Latin texts predating the 8th century.

Characteristics

The main difference between Old High German and the West Germanic dialects from which it developed is that it underwent the Second Sound Shift or High German consonant shift. This is generally dated approximately to the late 5th and early 6th centuries—hence dating its start to around 500 AD. The result of this sound change is that the consonantal system of German remains different from all other West Germanic languages, including English and Low German. Grammatically, however, Old High German remained very similar to Old English, Old Dutch, and Old Saxon.

The American Heritage Dictionary of the English Language

The American Heritage Dictionary of the English Language (AHD) is an American dictionary of English published by Boston publisher Houghton Mifflin, the first edition of which appeared in 1969. Its creation was spurred by the controversy over the Webster's Third New International Dictionary.

History

James Parton, the publisher (and co-owner) of the history magazine American Heritage, was appalled by the permissiveness of Webster's Third, published in 1961, and tried to buy the G. and C. Merriam Company so he could undo the changes. When that failed, he contracted with Houghton to publish a new dictionary. The AHD was edited by William Morris and relied on a usage panel of 105 writers, speakers, and eminent persons chosen for their well-known conservatism in the use of language. However, Morris made inconsistent use of the panels, often ignoring their advice and inserting his own opinions.

Linguistics

The AHD broke ground among dictionaries by using corpus linguistics for compiling word-frequencies and other information. It took the innovative step of combining prescriptive information (how language should be used) and descriptive information (how it actually is used). The descriptive information was derived from actual texts.
