 12 PREFACE

namic syllable or breth-impuls thus begins within a sound, the sound is cald double or geminated, and is, thruout this dictionary, represented (as here) by two separate letters.

When, as is always the case at the inception of a static syllable, the intersyllabic though lies within the limits of a single sound (of minimum sonenty), as, in the word better ('betaz), within the [t], the letter representing this sound of minimum sonenty sufficiently indicates the position of the intersyllabic though. It is neither necessary nor beneficial further to indicate its position, for unless in uttering the word a new breth-impuls is gratuitously introduced, or some error made in the sounds themselvs, the correct pronunciation will necessarily result.

When, en the other hand, as is always the case at the in- ception of a dynamic syllable, the intersyllabic though lies just before a certain sound, as before the [b] in better or before the [b] or the [k] in baker, it is eften most necessary and beneficial to indicate its position. Thruout all the pronuncia- tions in this dictionary this intersyllabic tjough is, except initially or where alredy indicated by a stjess-mark (see just below, in the paragraf en Stress), indicated by means of a hyfen or impuls-mark (-).

Stress. Stress, or dynamic accent, is the relativ emfasis with which a sound, syllable, or sequence of syllables is ut- terd. It is the intensity or degree of energy characterizing a breth-impuls used in speech. It is the force or vigor im- parted to any given utterance by the breth.

In this dictionary the starting-point of every syllable hav- ing chief stress (that is, having the primary degree of force of a new or reinforced breth-impuls) is always indicated by means of a special symbol, the chief stjess-mark ('), placed just before the stjest syllable; and the starting-peint of every syllable having secondary stjess is, wherever practicable, in- dicated by means of the secondary stes9*mark placed just before the st^est syllable. The starting-points of other nen# initial dynamic syllables having only tertiary, quarternary, or other weak stress, are left unmarkt except by the hyfen or
