How many syllables does the word comfortable have?

Answer 1

In written form it appears to have four 'com.for.ta.ble' and some native speakers do pronounce it with all four /ˈkʌmfərtəbəl/. However, it is also correct and more common for the second 'o' and 'r' to be silent leading to the pronunciation being more like 'comf.ta.ble' /ˈkʌmftəbəl/.

The general American pronunciation also gives the word three syllables, but differently. The 'r' and the 't' switch places (a process known as "metathesis"), yielding the pronunciation 'comf-tar-ble' /ˈkʌmftərbəl/.
