Lexicography

Principles of Lexicography

To gain a better understanding of the principles of lexicography, we should be familiar with the term lexeme.

Lexemes, also called word stems, are minimal units of lexical meaning that connect related forms of a word.

All the inflected versions of a lexeme (took, taken, etc.) are subordinate to the lexeme. So, in a dictionary, there would only be an entry for the word take (and not entries for the inflected versions).

Lexemes are then assembled into a lexicon, which is a compilation of words in a language and their meanings. A lexicon is essentially the established vocabulary of a language or branch of knowledge (i.e. medical, legal, etc.).

In the twenty-first century, few people actually use a hard copy of a dictionary and instead opt for the electronic version. This has ushered in an age of electronic lexicography, or e-lexicography. Traditional reference sources such as Merriam-Webster's Dictionary and Encyclopædia Britannica now offer their content online.

Types of Lexicography

Whether we’re discussing traditional or e-lexicography, there are two types of lexicography: theoretical and practical.

Theoretical Lexicography

Theoretical lexicography is the study or description of dictionary organization. In other words, theoretical lexicography analyzes the vocabulary of a particular language and the way the lexicon is arranged. The goal is to create better, more user-friendly dictionaries in the future.

This type of lexicography serves to develop theories about structural and semantic associations among words in a dictionary. For example, Taber's Medical Dictionary is a specialized dictionary of medical terms for medical and legal professionals, and theoretical lexicography’s aim is to arrange those terms in such a way that would most benefit these users.

Taber’s Medical Dictionary pairs the medical lexicon "systole" (contraction of the chambers of the heart) with seven other associated medical conditions such as "aborted systole," "anticipated systole," and so on. This was an intentional choice by lexicographers based on principles of theoretical lexicography; it provides context so persons studying the term "systole" will be familiar with these related conditions.

Practical Lexicography

Practical lexicography is the applied discipline of writing, editing, and compiling words for generalized and specialized use in a dictionary. The aim of practical lexicography is to create an accurate and informative reference text that is a reliable asset to students and speakers of the language.

Merriam-Webster’s Dictionary is a good example of practical lexicography in use. The reputation of this dictionary is above reproach due in part to how long it’s been in print (and electronic use). Merriam-Webster’s Dictionary was printed as the United States' first unabridged dictionary in 1806, and it has since established itself as an authority in the realm of practical lexicography.

Lexicography and Lexicology

A quick note on the difference between lexicography and lexicology, as these terms may easily be confused with one another:

Lexicography, as we’ve established, is the process of compiling a dictionary. Lexicology, on the other hand, is the study of vocabulary. While these two areas of study are intertwined, since lexicography necessarily involves vocabulary, lexicology isn’t concerned with the arrangement of a lexicon.

Lexicology studies things like word etymology and morphological structures, the form, meaning, and use of words. You might think of lexicology as a level of language study, while lexicography is the technique of compiling and distinguishing the words of a language.

History of English Lexicography

The history of English lexicography begins with the foundation of the practice of lexicology, which dates back to ancient Sumeria (3200 BC). During this time, lists of words were printed on clay tablets to teach people cuneiform, an ancient writing system. As languages and cultures intermingled over time, lexicography came to include translations and specific criteria for the lexemes, such as proper spelling and pronunciation.

We can trace the history of English lexicography back to the Old English period (5th century). This was a time when the language of the Roman church was Latin, which meant its priests needed to be knowledgeable in the language to read the bible. As the English-speaking monks learned and read these manuscripts, they would write single-word translations in the margins for themselves and future readers. This is believed to be the beginning of (bilingual) lexicography in English.
