פ.ת.ח.
 
Perhaps you know the word לִפְתּוֹח (leef-TOH-ah) – to open. If you’re familiar with Jewish prayer, you more than likely know the verse פּוֹתֵחַ אֶת יָדֶךָ וּמַשְׂבִּיעַ לְכָל חָי רָצוֹן (poh-TEH-ah et yah-DEH-khah oo-mahs-BEE-ah le-KHOL khai rah-TSOHN) – You open your hand and satiate all those that live with favor.
 
The Hebrew word for develop as in, this child is developing fast, is לְהִתְפַּתֵח (le-heet-pah-TEH-ah).
 
However, to develop something else, it’s לְפַתֵּח (le-fah-TEH-ah). For example, אֲנִי מְפַתֵּחַ קוּרְסִים בְּעִבְרִית (ah-NEE me-fah-TEH-ah KOOR-seem be-eev-REET) – I develop courses in Hebrew (language).
