The spelling of the word "dis plant" may seem unusual, but it actually reflects the pronunciation of the phrase "this plant" in some dialects. The IPA phonetic transcription for "dis plant" would be /dɪs plænt/, with the "d" sound at the beginning replaced by a voiced dental fricative /ð/ in some dialects. The use of non-standard spellings in informal communication like texts or chats is common, but it is important to use correct spelling in formal writing.
