Rules of English part-of-speech conversion

Adding -y after 1. nouns can become adjectives (especially some weather-related nouns). For example: rain-rain, cloud-cloud, wind-wind, snow-snow, health-health, luck-luck, etc.

Note: 1) If the noun ends with an stressed closed syllable and there is only one consonant at the end, the consonant at the end should be written in double, and then -y should be added. Such as: sun-sunny, fun-fun, etc.

2) When a few nouns ending in the silent e become adjectives, the e should be removed and -y should be added. For example: noise, icing, etc.

2. Some abstract nouns can become adjectives by adding -ful at the end. For example: caring-caring, thanking-thanking, helping-helping, using-useful, beautiful-beautiful, etc.

3. Some nouns indicating a country can be added with -ese, -ish or -n at the end to form adjectives indicating nationality and language. For example: China-China, Japan-Japan, Britain-Britain, America-America, India-India, Australia-Australia (note Canada-Canada).

4. Add -ous after nouns to become adjectives. For example: danger-danger, etc.

5. Add -ly after nouns to become adjectives. For example: friendly friends, lovely love and so on.

6. Adding -less after a noun constitutes an adjective with negative meaning. For example: care-carelessness, use-uselessness, hope-hopelessness, home-homelessness, etc.

7. For some nouns ending in -ence, change "ence" into "ent" and become adjectives. For example: different-different, silence-silence, etc.

Second, the method of changing verbs into nouns.

1. The word form remains unchanged and the part of speech changes. Such as work, study, water, plants and so on. Can be used as a verb or noun.

2. After adding -er or -or at the end of some verbs, they become nouns that mean "a certain kind of people". For example: workers, teachers, singers, high jumpers, players, learners, visitors, inventors and so on.

Note: 1) Verbs end with a silent e and -r at the end. For example: drive-drive-driver, write-writer, etc.

2) Verbs that end with a stressed closed syllable and have only one consonant at the end should be written with -er. For example: run-run-runner, win-winner, begin beginner, etc.

3. Add -ing becomes a noun after the verb (in the same way as the verb becomes a present participle). For example: meeting-meeting, building-building, waiting-waiting, washing-washing, swimming-swimming, shopping-shopping, starting-starting, etc.

Third, the method of changing adjectives into adverbs.

Generally speaking, adding -ly after adjectives can become adverbs. For example: fast-fast, slow-slow, loud-loud, sudden-sudden, etc. However, the following points are worth noting:

1. Some adjectives ending in "consonant +y" should be changed from y to I and then to -ly. For example: happy-happy, angry-angry, lucky-lucky, heavy-heavy, noisy-noisy and so on.

2. For some adjectives ending in -ble or -le, remove e and add -y ... for example, possible-possible, terrible-terrible and so on.

Several adjectives ending in e should be removed and added. For example: true-true, and so on. But most adjectives ending in e are still added directly. For example: polite-polite, broad-broad, etc.

4. When an adjective ending in -l becomes an adverb, you should still add -ly at the end of the word, instead of just adding -y ... Unless it ends in -ll, only add -y at the end of the word. For example: normal-normal, careful-careful, useful-useful, complete-sufficient, etc.
