If the letter is at the end of a word the symbol is drawn differently. However, it does not change the pronunciation or transliteration in any way. The name for the letter is, Final Kaf (Kaf Sofit). There are four other Hebrew letters that take final forms, Tsadi, Mem, Nun, and Pei. Kaf/khaf is the only Hebrew letter that can take a vowel in its word-final form that is pronounced after the consonant, that vowel being the qamatz.
The letter is named kāf, and is written in several ways depending on its position in the word (these are the standard letter forms used for the Western variants of the Arabic language):
Position in word:
It also has a long variant form, which is not distinguished in the Arabic language, but may be seen more frequently in other languages than Arabic (and it is used consistently for the Sindhi language, see below):
In Literary Arabic, Kaf is used as a prefix meaning "like", "as", or "as though". For example, كَطَائِر (/katˤaːʔir/), meaning "like a bird" or "as though a bird" (as in Hebrew, above). The prefix كَـka is one of the Arabic words for "like" or "as" (the other, مِثْل/miθl/, is unrelated). The /ka/ prefix sometimes has been added to other words to create fixed constructions. For instance, it is prefixed to ﺫَلِك/ðaːlik/ "this, that" to form the fixed word كَذَلِك/kaðaːlik/ "like so, likewise."
Kaf is used as a possessive suffix for second-person singular nouns (feminine taking kāf-kasrahكِ, /ki/ and masculine kāf-fatḥahكَ/ka/); for instance, كِتَابkitāb ("book") becomes كِتَابُكَkitābuka ("your book", where the person spoken to is masculine) كِتَابُكِkitābuki ("your book", where the person spoken to is feminine). At the ends of sentences and often in conversation the final vowel is suppressed, and thus كِتَابُكkitābuk ("your book"). In several varieties of vernacular Arabic, however, the kaf with no harakat is the standard second-person possessive, with the Literary Arabic harakah shifted to the letter before the kaf: thus masculine "your book" in these varieties is كِتَابَكkitābak and feminine "your book" كِتَابِكkitābik.
In the Persian alphabet and the Urdu alphabet, "Kaph" has slightly different isolated or final forms from the Mashriqi Arabic (ک as opposed to ك) and thus takes a different codepoint in Unicode. But it uses the same final form as the Maghrebi style Arabic. These simplified forms are shown here:

In addition, these variants are used distinctly in the Sindhi as separate letters, to differentiate khē (using the simplified forms) from kāf (written in Sindhi with the long variant form shown in the subsection above).
