+# Hints
+
+## General
+
+- The Python Docs [Tutorial for strings][python-str-doc] has an overview of the Python `str` type.
+- String methods [`str.join()`][str-join] and [`str.split()`][str-split] ar very helpful when processing strings.
+- The Python Docs on [Sequence Types][common sequence operations] has a rundown of operations common to all sequences, including `strings`, `lists`, `tuples`, and `ranges`.
+
+There's four activities in the assignment, each with a set of text or words to work with.
+
+## 1. Add a prefix to a word
+
+- Small strings can be concatenated with the `+` operator.
+
+## 2. Add prefixes to word groups
+
+- Believe it or not, [`str.join()`][str-join] is all you need here.  **A loop is not required**.
+- The tests will be feeding your function a `list`.  There will be no need to alter this `list` if you can figure out a good delimiter string.
+- Remember that delimiter strings go between elements and "glue" them together into a single string. Delimiters are inserted _without_ space, although you can include space characters within them.
+- Like [`str.split()`][str-split], `str.join()` can process an arbitrary-length string, made up of any unicode code points. _Unlike_ `str.split()`, it can also process arbitrary-length iterables like `list`, `tuple`, and `set`.
+
+## 3. Remove a suffix from a word
+
+- Strings can be indexed or sliced from either the left (starting at 0) or the right (starting at -1).
+- If you want the last code point of an arbitrary-length string, you can use `[-1]`.
+- The last three letters in a string can be "sliced off" using a negative index. e.g. `beautiful'[:-3] == 'beauti`
+
+## 4. Extract and transform a word
+
+- Using [`str.split()`][str-split] returns a `list` of strings broken on white space.
+- `lists` are sequences, and can be indexed.
+- [`str.split()`][str-split] can be directly indexed: `'Exercism rocks!'.split()[0] == 'Exercism'`
+- Be careful of punctuation! Periods can be removed via slice: `'dark.'[:-1] == 'dark'`
