I forgot to include theses last two sentences. Thank you.

1) The style of symbolist poets was characterized by the use of allusive language and development of the multiple association of words.
2) Furthermore, great importance was given to the sound of words as conveying “the music of ideas”.
3) They made use of quotations from foreign literature, indirect rather than direct statements and free verse.

3. comma needed after "statements" (#1 in the link I already gave you).

1 and 2 = OK

To find the answer to your question, you read a text or a source that provided information about symbolist poets and their style. The information you provided can be divided into three different points:

1) The style of symbolist poets involved the use of allusive language and the development of multiple associations of words. Symbolist poets were known for using language that hinted at or suggested deeper meanings, often through the use of metaphors, symbols, and imagery. They sought to evoke emotions and ideas indirectly, rather than explicitly stating them.

2) Another important characteristic of symbolist poetry was the emphasis on the sound of words. Symbolist poets believed that the musical quality of language could convey the "music of ideas." They paid close attention to the rhythm and the sounds of words, aiming to create a harmonious and aesthetically pleasing experience for the reader or listener.

3) Symbolist poets drew inspiration from foreign literature and utilized quotations from these works in their own poetry. They preferred indirect statements, allowing readers to interpret the meaning and form their own connections. Symbolist poets were also known for their use of free verse, which lacks a regular rhyme scheme or metrical pattern, giving them more flexibility in expressing their ideas.

In conclusion, the style of symbolist poets involved the use of allusive language, the emphasis on the sound of words, indirect statements, and free verse. These elements allowed them to create rich and evocative poetry that explored complex emotions and ideas.
