Prefixes and Suffixes in Medical Terminology پیشوندها و پسوندها در اصطلاحات پزشکی

درس امروز پیشوندها و پسوندها در اصطلاحات پزشکیه  ! گرامرم خوب نیست اما میدونم که ریشه یک لغت یعنی عنصر اساسی ای که در همه اشکال دیگر لغت مشترکه . پیشوند شکلیه که در ابتدای ریشه  مستقر میشه و پسوند شکلیه که در انتهای ریشه قرار میگیره . درک اصطلاحات پزشکی بدون این پیشوند و پسوندها غیر ممکنه . فهرستی از پیشوندها و پسوندها رو در اختیار عزیزان قرار میدم . در فهرست ذیل اول پیشوندها و یا پسوندها قید و بعدش  معنی اون نوشته شده و در داخل پرانتز یک یا دو مثال وجود داره . برای ترجمه لغات میتونین از مترجم گوگل  و اگه انگلیسیتان خوب باشه میتونین از سایت فری دیکشنری استفاده کنید . البته در دیکشنریهای فارسی ، چندین اشتباه در تشریح بیماریها دیده ام ،  لذا در اینگونه مطالب سعی کنین از دیکشنری انگلیسی به انگلیسی استفاده کنین :
