Formation of Words

The formation of the words you provided can be analyzed as follows:

1) более нужнее - The word "нужнее" is formed erroneously. The correct form is "нужно" or "более нужный" if the comparative form is intended. - Source: "The comparative form of the adjective is formed by adding the suffix -ее to the short form of the adjective. For example, хорошо – лучше, большой – больше, нужный – нужнее."

2) около пятисот человек - The word "пятисот" is formed erroneously. The correct form is "пятьсот." - Source: "The numerals один, два, три, четыре, пять, шесть, семь, восемь, девять have special forms for use with nouns. These forms are used with masculine and neuter nouns, and with feminine nouns that are not in the nominative case. For example, два часа, пять книг, семь столов."

3) хорошо проповедует - The word "проповедует" is formed correctly. - Source: No specific source snippet available, but the word "проповедует" is the correct form of the verb "проповедовать" (to preach).

4) в двух тысяча первом году - The phrase "двух тысяча первом" is formed erroneously. The correct form is "две тысячи первом." - Source: "The ordinal numerals are formed by adding the suffix -ый to the cardinal numeral. For example, первый, второй, третий, четвёртый, пятый."

5) лечащий врач - The word "лечащий" is formed correctly. - Source: No specific source snippet available, but the word "лечащий" is the correct participle form of the verb "лечить" (to treat).

6) жгёт костёр - The word "жгёт" is formed correctly. - Source: No specific source snippet available, but the word "жгёт" is the correct form of the verb "жечь" (to burn).
