a posture assumed by models for photographic or artistic purposes
pretend to be someone you are not; sometimes with fraudulent intentions; "She posed as the Czar's daughter"

having a bearing on or connection with the subject at issue; "the scientist corresponds with colleagues in order to learn about matters relevant to her own research"
