"Sedgier" is a comparative adjective used to describe something with more sedges, which are grass-like plants that grow in wet areas. The word is spelled with a soft "g" sound followed by an "ie" that says "ee" as in "bee". It is pronounced as /ˈsɛdʒ.iər/ in IPA phonetic transcription. When using comparatives in English, it is common to add "-ier" to the end of adjectives that are only one syllable or have the stress on the last syllable.
