It seemed inevitable that a clutching root, a sudden trunk or branch would end the ride in plunging disaster.

Thus, for example, the ending -ov becomes -ev for nouns whose roots end in the above letters.

Inflection -ing of those verbs with roots ending in -e which do not drop the e (being, seeing, swingeing, etc.)

If the verbal root ends in a vowel, the two vowels may merge or contract.

The root of sorrow plucked; then ends rebirth.

The d is omitted if the root ends with an obstruent or nasal consonant: dut 'two', dut.

The declension of a noun depends on whether the root of the noun ends with a vowel or a consonant.

Consonant stems are the root (roots end in consonants).

With verbs whose roots end in el or er, the e of the infinitive suffix is dropped.

So if the spelled root ends in a silent letter, this letter should be ignored in applying the rule.
