Page Contents: Preface | Notes for the User | Formulations Commonly Used in Beilstein


The Beilstein Dictionary (German/English) has been compiled by the scientific staff of the Beilstein Institute to facilitate the use of Basic Series and Supplementary Series I to IV by those Handbook users whose native language is not German. With a total of about 2,100 entries, it contains most German words occurring in the Beilstein Handbook, as well as common abbreviations, alphabetically listed with their English equivalents.

An appended supplement (page 59 onwards) lists a series of “standard formulations” frequently used in Beilstein, together with their English translations.

It is our hope that this glossary will prove of assistance to the non German-speaking user of Beilstein, in overcoming any language difficulties which may be encountered.

Notes for the User

The English equivalents of German words appearing in the Beilstein Handbook are chosen such that in each case the most usual translation in the context of the Handbook of Organic Chemistry is listed first, followed by other possibilities which can also occur in this context. The equivalents of a particular German word which are not relevant to this context are not included; e.g. the word “mittelstandig” in a chemical text would almost invariably mean “in the middle or central position” and NOT “middle class” which is the everyday meaning of the word.

German words whose spelling is identical to the English or so similar that confusion is unlikely to arise are generally not included; e.g. the German words “Potential” and “Elektrode” are not listed. Synonyms of English words are not given when their meaning is identical to the word listed; e.g. German “nahe” is translated by the word “near”; the synonym “close”, which is identical in meaning, is not given.

Where a German word can have several different translations according to the context in which it occurs (within the wider context of the Handbook), or where the English word given is open to misinterpretation, an explanatory note is provided in brackets; e.g. German “abhandeln” is translated as “treat”, the words “a topic or subject” are given in brackets to indicate the usage of this word, which cannot, for example, mean treat a patient, or, treat a solid with a liquid, etc.

Past participles and other parts of verbs which may not be immediately recognizable from the infinitive form are listed separately at the appropriate place (alphabetically); e.g. 'ist' (is) will be found as well as “sein” (to be).

The preposition “to”, indicating the infinitive form, is included before all English verbs. This enables the user to identify the German word immediately as a verb.

Nouns in German, as in many other languages, with the notable exception of English, are associated with a GENDER, masculine (m), feminine (f) or neuter (n), even though the noun may refer to an inanimate object or an abstract idea. The genders of all nouns included in this vocabulary are indicated by the appropriate letter in brackets behind the German word. This is not only useful for the user who has some knowledge of German but also enables immediate recognition of a noun. Another feature which facilitates recognition of German nouns is that they are all invariably written with a capital letter (not just proper nouns as in English).

Most “longer” German words (usually nouns) are compound words formed by simply writing two (or occasionally more) shorter words together (to form a new idea associated with both of them), but without a space or hyphen as is usual in English.

For example, “reaction vessel” would be written “Reaktionsgefass” in German, i.e. “reaktion” (reaction) plus “Gefass” (vessel). The additional “s” or sometimes “n” between two words merely acts as a link without further significance.

In order to make such “double” nouns easier to read for users of this vocabulary who are unfamiliar with them, they are printed with a hyphen between them, e.g. “Reaktionsgefass” is written “Reaktions-gefass”, (clearly indicating the association of ideas), although in the text of the Handbook the two words are more commonly to be found in the composite form without the hyphen. German words beginning with a modified vowel (a,o,u) are to be found immediately after those beginning with the corresponding unmodified vowel. e.g. ab before ab before ac before ac, etc.

The letters double ‘s’ can be written in two ways in German, either as ss or as ß (similar to the Greek beta), according to a special set of rules (which are of no interest to the non-linguist). In order to simplify matters for the non German-speaker and avoid confusion, only the ss form is used in this dictionary.
