@userunknown of course: GNU sed, installed by default on all versions of Ubuntu, has<and>for matching start-of-word and end-of-word. I suspect this is yet another Android question. OP has been know to post a number of questions about some Android app that provides Unix commands, while pretending it is Ubuntu OP is using.

For removing the word foggy in above scenario, you don't need start-of-word/end-of-word-markers.

In the above string, you don't need start-of-word/end-of-word markers and you may use:
echo 'foggy light' | sed 's/foggy//g'
For the additional question in the comment:
Indeeed, my sed version
sed --version
sed (GNU sed) 4.2.2
supports the Syntax with <...>
echo 'foggy foggylight' | sed 's/<foggy>//g'
foggylight
If it doesn't work for you, report your sed version and read its manpage. For my sed, this syntax works too:
echo 'foggy foggylight' | sed 's/bfoggyb//g'
foggylight
b can be memorized as boundary.
