(d)
The vowel ёis always stressed, e.g. in полёт, flight . It follows that ё
cannot occur if the stress in a word is on any other syllable (contrast пойд ёшь and вы´йд eшь).

Consonant changes
A number of consonants (e.g. the velars г, к, х) are changed in certain circumstances into consonants of a different type (e.g. the hushing
consonants ж, ч, ш). Thus it commonly happens that the consonant with which a root ends is transformed into a different consonant when certain suffixes are added to the root or when certain adjectival or verbal flexions are added to it (see 9.3.3, 9.6.8).
The main changes, which will be encountered frequently in the
examples given in the following sections, are:
г → ж, as in дви жe´ниe, movement , from the root двиг
д → ж, as in бро жe´ниe, ferment , from the root брод
д → жд, as in освобо ждe´ниe, liberation , from the root свобо´д
з → ж, as in вырa жe´ниe, expression , from the root рaз
к → ч, as in восто´ чный, eastern , from восто´к
c → ш, as in отно шe´ниe, attitude , from the root нос
ст → щ, as in чи´ щe, cleaner , from the root чист
т → ч, as in лe чу, I fly , from лeтe´ть
т → щ, as in освe щe´ниe, illumination , from the root свeт
x → ш, as in ти шинa´, tranquillity , from the root тих
8.2.6
Epenthetic л
Before certain suffixes or flexions the consonant л is added to a root ending in б, в, м, п, ф, e.g.
у/глуб/ л/e´ниe, deepening
у/див/ л/e´ниe, surprise
из/ум/ л/e´ниe, astonishment
куп/ л/ю´, I shall buy
рaз/грaф/ л/ю´, I shall rule (lines on paper)

Verbal prefixes
There are some two dozen prefixes which may be added to a simple
verb in order to modify its meaning or to create a verb with a related but different meaning. A few of these prefixes are to be found in
only a small number of verbs, but the majority occur in many
verbs.
Most of the common prefixes may be used in various senses. They
may indicate the direction of the movement denoted by the basic
verb (e.g. входи´ть, to go into ), or they may in some other way define the precise nature of the action denoted by the verb (e.g. зaплa´кaть,
to startto cry ). In many instances the prefix, perhaps combined with some other affix, bears a subtle meaning which in English must be
rendered by some adverbial modification of the verb (e.g. зaстрeли´ть, to shoot dead ; нaбe´гaть ся, to have had enoughof running about ; 255

посви´ст ывaть, to whistle from time to time ; приоткры´ть, to open
slightly ).
Note 1
Prefix and aspect: normally the addition of a prefix to a simple imperfective verb makes the verb perfective, e.g. писa´ть (impf ), нaписa´ть (pf ); вязa´ть
(impf ), связa´ть (pf ). In some instances (e.g. in the verb нaписa´ть) the prefix has no function other than to make the verb perfective (i.e. it adds only the sense of completeness of the action to the sense already conveyed by the imperfective). However, in other instances (e.g. in the verb связa´ть) the prefix provides a further modification of the meaning ( вязa´тьmeans to tie , but связa´тьmeans to tie together , i.e. to unite, to join, to link ). (See also 8.6 on
infixes.)

Prefixes consisting of a single consonant or ending in a consonant may have to add ofor the sake of euphony, e.g. во-, подо-.
Most of the prefixes which verbs may bear are listed below. A
few of the less common meanings which may be borne by some
of the prefixes are omitted. The directional meaning of each prefix, if the prefix has such a meaning, is dealt with first in each
instance.
